I purchased a pair of headlights for my mercedes-benz. They worked great for a few months then the right low beam stopped working. I brought it to an experienced European technician, expecting it to be a harness, or the ballast. However it was just the headlight itself. When I tried to contact them about getting it replaced, they claimed that it was the wrong headlight for my car... even though it had been working for months, and an experienced mechanic says they are the right fit. When I try to tell them that they are wrong, they endlessly transfer me between agents and stop talking with me. Absolutely unbelievable! That's nearly $400 down the drain!
