Did they have a sign or a statement on any papers that said no refunds, only store credit? A lot of times people dont pay attention to the small writing and screw themselves that way. Regardless, you paid for it and if it was in good working order, you still would not have returned it correct? You said they picked the motor up the same day you traded in your lightning (which you then knew you had no intentions of using the motor). I'm not sticking up for them, just saying that I can relate as I hate when people buy shit and return it months later for the typical "I dont need it anymore" response. If he said ok no problem over the phone, what does that exactly implicate? If he did not specifically say "no problem sir, we will return the full amount back on to your card", then his statement of "ok no problem" doesnt mean shit in court.
