My ethernet port is not working

Question

I recently had my macbook sent into the store to repair a bad logic board (fried in a thunderstorm) and over the past month I have noticed that my ethernet port wasn't working. Before the storms our router was acting up so I figured our maintenance was working. When I noticed the bandwidth slowing I checked my ethernet connection only to find I have been using wireless this whole time.
Now I'm not sure if the apple store technicians (it was actually shipped off site to be repaired) checked the ethernet port when I last sent it in because from my knowledge it was working before the storm and I had never checked it afterwards.. I really don't want to be charged another $200 to fix a problem that could have been fixed during the same time as my previous work order.
I also had a bad experience with their timely service, my macbook was there for about a week and a half with no progress on anything when it was supposed to be shipped off site and when it finally was shipped off site it took a matter of two days to be fixed. That would have been two weeks less than my month turn over for this repair.
Any help or suggestions on what I should do and how I should approach the apple store? I really do not want a repeat and cannot afford to turn my macbook taken from me as it is being used for my current job.
P.S. I have singled the ethernet port to my computer as I had used my dad's macbook on the same ethernet cord and his worked, mine did not.

I have updated my computer this morning, it didn't change anything regarding the ethernet port. I also logged onto my windows through bootcamp and ran ipconfig. When I look into the ethernet option it says "media disconnected" could this mean the port is simply loose? or would there be a different sentence there if it was actually damaged. When I went under profiler though it did not say no ethernet ports are found but just listed off the usual numbers.
I'm tempted to reset my SMC but I want to make sure it will have no side effects on my computer, I really hope I can talk to the apple store because I'm really sick of their service to me.
I'm going to ramble for a bit but I feel like I got taken advantage of because I cannot be pushy or rude to others even in inconvenience. It was ~$100 for the repair service which isn't terrible and ~$130 for a new logic board togehter I ended up paying just under $300 for the complete repair which on it's own is not horrible either. However my computer was stuck in their system for a little over a month, it took 1 week to get the diagnosis which from there it should have been shipped off site to be repaired (and if followed how much time it took later on I would have been two days until I had my computer back) however every time I checked the status and called in the genius' replied it has been shipped off site so the status will not update until a repair has been finished. after a week of bombarding people at the apple store with phone calls asking how my computer is doing I finally got a call saying "it has been a week since we have heard from you about your computer, would you like for it to be repaired?". This was unbelievable all of my phone calls did not go through (was around 20 or so multiple ones in a day) and I wasted a week just to find my computer was basically lost in their store. Finally it was shipped off and repaired and sent back to me. When I brought this up to the manager in store she simply stated that there was no confirmation to repair the computer until I answered that phone call over a week later, which is absolutely ridiculous.
I received no other help from that point and ended up paying the full bill (which wasn't my purpose but still..) and I refuse to be treated like that again when it was supposed to be a somewhat simple procedure.
end rant.
Anyway, I really hope this works because I do not feel like repeating this event nor paying another ~100 service fee for something that could have been repaired during the same time.
