I am not happy with apple support

Question

MacBook Pro (13-inch Early 2011)
Serial number C0*******H2H
I bought apple MacBook pro 2011, One night I put my MacBook on standby mode when I wake up in morning it's power is off, not starting at all I tried all the things but still it is not working.
But I thought apple can help me to solve this issue as I spent lot of money for this product and also buy 3 years protection plan in advance to make sure if I got any issue then it will be taken care of by apple.
When I go to service station they told me your unit is tempered and we are not sure you cover in apple warranty or not, I am totally surprised, yes I try to change my Hard disk and RAM as I want to use SSD and more RAM, but I did the same thing with my other laptops as well but nobody told me your unit is tempered.
I try to explain this to service station but they speak in very rude way and told me unit cannot be covered in warranty.
After a long discussion they are agree to talk with apple but within two days they reply same thing, I feel like cheated as when I bought mac book they told me just buy this protection plan and forget everything.
Me and my company using a lot of apple products and we believe in Apple support that’s why we spent a lot of money on apple products but now I have to think again and reconsider my decision as other companies giving us a very good offer.
I am also thinking to return back my all apple products and recommend to my company not to buy anything from apple in future, because now apple is not an extra ordinary company.
I am very sorry to say that now it is not important for me, you repair or replace my unit, because I do not know I can believe on apple product or not.

Answer 1

Yes I also think replacing RAM and hard disk not void the warranty, but I got this reply from service station they do not want to share anything they talk with apple support, we told him At least give us proper reason but they repeated same thing again and again, if you cannot give solution then you must tell reason to customer.
And one most important thing why I should by Apple protection plan as it is not covering this very simple problem, I think it is totally wastage of money, Other companies service center and support is more reliable then apple. When I ask them OK it is not cover in Warranty could you tell me how much repair cost, they told me it is about 1000 $, by the same you can bought a new Macbook, that means only one part cost is equal to new mac then all other things in Macbook is free ?
And you told me you know only one side story, Yes it’s true but I think Apple is not audit their service stations, they never check Is service station people helping the customer or irritating the customer.
