I was in the market for a MacBook and based on the reviews I had seen here, figured I could save some money by getting a renewed one. The laptop arrived and ran decently well, but it was immediately apparent that the battery was no good. It would get very hot, and die in just over an hour if I was actively using it. I thought maybe I could get by if I lowered the brightness, ran few applications, etc. The battery was still dying way too quick so I decided to return.When I returned my refund was $500 dollars short. The seller apparently charged a $500 dollar restocking fee without informing me, because the return was past 30 days - despite this product explicitly being backed by the 90-day Amazon Renewed Guarantee.It has now been over three weeks since I returned the item. In that time I have spoke to five different Amazon customer service representatives over phone, email, and chat. Each time I have been assured that I will have a response in 48 hours, and when I call to check I am told no claim was filed. This experience has been beyond frustrating and I would stay away from this seller and Amazon Renewed.
