I bought a camera with accessories. They shipped a wrong tripod and charger. The "professional" parts turned out to be nameless and brandless boxes, making me wonder about quality. The 4-year warranty was with a fly-by-night company.
The camera I bought (a Sony, amazingly) took very poor motion pictures. I asked to have the wrong parts remedied, and spent many hours waiting on hold, being passed from person to person. Finally I demanded an RMA. After many more days and hours, I got the RMA. I returned everything.
The customer service department had assured me that I would only be charged a 10% restock fee on what I had ordered and what had been properly shipped. When the credit came through, they took $254 off of my $1836 purchase. They never even sent me any paperwork. When complained, they said that some fine print on their site qualifies them to take "an additional 6% for shipping" on returns. In fact, they had already charged me for shipping the original order. It is a line item on my invoice.
When I complained about this treatment, they put me back into the voicemail tree and wasted time until I finally gave up. I have reported them to the Better Business Bureau.
They still owe me $150.
