Well of course I think we are all sorry for your experience but this is inherent in buying used merchandise of any type, category, or price and it is possible if not even most likely that the dealer and the manufacturer are not at all directly responsible for what happened they may not know it's history themselves and it may have even been subject to abuse or extreme wear but not visually apparent or detectable. Repairs
such as may be necessary, required, or desirable
and their associated costs, shipping, and inconvenience are a risk you take when you buy used and you actually should be happy if any and all required replacement parts are available.
