X1 Carbon - Come on, Lenovo. A little conscienti​ousness, please.

Question

I would like to express my disappointment in Lenovo's product and their lack of apt customer service.
I bought my X1 Carbon (adaptive keyboard) in Singapore while on holiday sometime late March.  I started using it mid-April.  I am currently residing in the Philippines. 
In the beggining, I had no issues with the unit.  Come late May, the screen started flickering in and out, accompanied by glitches and static formations - this happened usually when the device was running with a heavier load.  Apart from flickering, I noticed that the screen was a tad dim despite being at full brightness.
Come early July, I contacted the service hotline (redirected to call center in Malaysia) to explain my concern.  The customer representative concisely told me that a technician from their partner in the Philippines would contact me very soon and drop by to wherever I am to repair the unit.  That I had nothing to worry about.  Clearly the customer representative knew this to be a known concern as he had very few questions before concluding his diagnosis of my unit.
The wait was more than 2 weeks before I contacted the service hotline again, expressing concern that nobody got back to me despite getting an assurance that my issue would be resolved expeditiously.  This representative assured me that someone from their service center partner would contact me within the day.
This still did not happen so I procured the number of their service partner and made the call myself.  After much confusion and a lot of time sapped, we finally got on the same page and they found that, indeed, I had a pending case and that they are waiting for an LCD Panel and LCD Cable for my unit.  A few days later, on August 01, 2014, the technician was in front of me, tinkering with my laptop in an attempt to replace the parts.
As an aside, I asked the technician why the paint on the screws on the bottom of my supposedly brand new unit was faded.  He told me that my unit was likely not exactly brand new but a repaired-brand new unit.  That when shops receive a unit, they run it for some time and if they see a problem, they repair it then sell it still.  A reason why I went to an authorized Lenovo dealer was precisely because I wanted to relax in the idea that I would receive a laptop that corresponded to the price and hassles I went through.  Certainly not a repaired unit.
While the technician was attempting to dismantle my laptop, I saw that he had a hard time.  I asked him why and he said it was his first time handling a unit like mine.  This did not sit well with me, as I am sure it would not with most others.
When he got to replacing the LCD Panel, I saw that the panel that came with my laptop had a lot of black fingerprint smudges on it.  Does this not say something about the Production Process and Quality Control?
Further, he realized that the LCD Cable supplied him was not compatible with my unit so he decided to use the old cable, in hopes that the LCD Panel was the only culprit in the flickering issue.
When he put everything back together, there was no display.  From a flickering screen to nothing.  He went and opened the unit up again to find out why - this took a few hours of trial and error, ending up in no display, over and over again.  Finally, as he was trying to remove the Panel again, he saw that he did not attach the LCD Cable properly.  He rectified and the unit worked but with the screen still dimmer than it should be - something he confirmed as a symptom of a faulty part, probably the LCD cable, he mentioned.
He told me that within 5 days, he would get the new LCD Cable to me, along with a sim card cover, which he damaged.  I followed up within those 5 days and the representative from Lenovo's service center partner tersely deflected my concern, telling me to go and call Lenovo as it was not their concern.
As I have been indisposed for some time, it is just now I have found the time to write this.  Nobody has gotten back to me since August 01, again, despite previous assurances.
In this post are an inordinate amount of concerns with Lenovo and their unit.  To summarize, and hopefully get some feedback and assistance:
- Authorized Lenovo seller in Singapore sold me a seemingly repaired unit - basis: paint on screws were faded, technician mentioned that it had indeed been opened (dealer S.O.P.) and battery portion was tinkered with, which led him to presume there was a previous battery concern.
- Lenovo service hotline and service supplier partner here apparently had flimsy coordination as I, the customer, had to call both parties up to follow-up on my concerns.  Took much longer than was promised.
- Wrong parts sent, technician, albeit seemingly capable with Lenovo laptops, had no experience with my unit.  Leading to hours of trial and error and damaging of a portion of housing (sim card cover).  And due to the sheer amount of moving around the hardware, seals within do not stick well within and a good bet that parts are looser than ought to be.
- Further weeks of waiting despite claims of getting the right part sent to me within 1 week.  Still waiting, into 3rd week now.
- Production process / quality control issue - black smudges on original LCD Panel.  Isn't this hazardous for the individuals in the production line?
- Oh, and what started everything - factory defect laptop, like many others on this board, with a dim and flickering screen.
Before I purchased this unit, I had, for some time, been looking to purchase my first Lenovo unit.  Hoping to experience that legendary workhorse quality and reliability.
Given its mid-range specifications, this unit is pretty expensive.  Imagine my disappointment when I paid a hefty price for a brand new device to later find out it was not only a repaired unit but a lemon in other parts of its hardware as well.
No replacement of unit, passed around by representatives who either did not care or were not qualified (I am clumping Lenovo's partners as part of Lenovo, yes), ridiculous amounts of waiting time, and still no resolution.
Overall, a top company with 3rd rate practices and service.  Simply indecent.

Answer 1

Mine shuts down randomly.
Post-sales: disconnected after 1.5 hours on hold. Thankfully I was doing work and had phone lying on my desk so I did not waste 1.5 hours of my time on hold.
Tried online chat - "call post sales"
Now called again and on hold for 35 minutes.
This is ridiculous. I paid through Amazon Payments - will contact Amazon and see if I can have any recourse through Amazon.
