Look people its just business. If someone does a good job/has a good experience with a business they tell maybe one or 2 people. If someone has a bad experience they tell everyone, thats why business' make it right. They go out of the way to make sure that the mistake on their part is resolved. Alex knew the ray was unhealthy, crap even my mother could tell that ray was unhealthy.
He was looking at this thread a ton of times (his name was at the bottom) and he just didn't know what to say. He knew he did something wrong. If he makes it right and refunds him or buys the ray back etc. then his reputation won't be tarnished or thrown off so quick.
I am just saying if the seller wants to work it out, fix the mistake, and keep his reputation, he has every opportunity to do so.
