Business ProfileforOWC

I purchased a used mac book from OWC on 02.20.24. after receiving the laptop and setting it up for business/ personal use, I noticed that the battery would drain within hours. I had purchased an extended warranty on the item and so contacted their support team immediately to try to resolve the issue. we spoke several times and none of the advice they gave me was making an improvement to the problem -- I was told I could return the laptop for a repair, replacement, or refund. I chose refund and was told that because of my warranty, there was not a time limit and I didn't have to rush to send it back. I received the return label on *****, and by ***** they had received the item. after repeated phone calls and emails to CS regarding the refund, I was finally told that a partial refund would be issued -- they could not find an issue with the battery upon inspection and were charging me a 15% restocking fee. In addition, it took 2 weeks to even receive that partial refund.a) if nothing was wrong with the battery and there was another cause for it not working at capacity, taking the steps to contact their "experts" should have resolved that b) at no point in time was I told that I had to adhere to a specific time frame for return -- in fact the opposite, I was told I didn't have to rush because I had purchased an extended warranty c) they are now claiming that nothing is wrong with the machine, and that because my return arrived ONE DAY later than their "return window" they are charging me a 15% restocking fee d) emails to the company have yielded no response, and in fact they did not even contact me to explain the refund -- I had to call them (and be placed on hold/ calls cut off for about an hour.)e) I would like the 15% charge refunded ($136.01) as I do not find it fair that I'm paying for bad advice from their support team.
