Apple MacBook Pro 13" (2019) (Open Box)

I bought a MacBook Pro August 12th. Upon arrival I was pretty disappointed of the horrible esthetic conditions. Dents, scratches but most of all the letters/keyboard where all mismatched. At closer look I realized that some of the letters/buttons had been replaced or covered by stickers. By September 7th I contacted the seller because the letters on the computer were interim not working, especially the letter N stoped working all together! Also the computer was overheating immediately. The seller took 4 days to reply but then accepted my warranty and asked if instead of a refund I would accept a Replacement and they would extend the warranty to 1 Year. I did accept the Replacement with 1 year warranty and on September 16th they shipped me a new one. When the replacement Mac Book Pro arrived I was surprised of the dirty conditions it arrived in, literally had food residue in between the key boards. The computer did not have major cosmetic issues and seem to work well. Yes it overheats some but that is not unusual for an older laptop. On October 7th I contacted the Seller because the lap top was no longer charging. On October 9th I got a reply saying they were terribly sorry about the issues and I could return it for a full refund....strange they did not mention an exchange!! Additionally mentioning that no refund/exchange would happen until the device was cleared. At this point i could not clear my computer because it had totally run out of power and I felt uncomfortable to send it to them when all my private info is in the laptop!! I then decided to go to Apple for an assessment/ diagnostic test. Apple was able to turn the computer back on a and assessed that 3 out of the 4 charging ports had failed and to fix the problem it would cost $126.28 I did not have the repair done at Apple yet because I wanted to ask the seller to cover the cost of the repair. The seller does not want to cover the cost, the seller wants to VOID my Warranty completely because I went to APPLE !! Just clarifying that I went to APPLE to have a Diagnostic/Quote, not repair (yet) I requested to escalate the situation with the head of service from the seller and Amazon. THE SELLER HAS STOPPED REPLYING TO MY MESSAGES... Beware of this seller.
