So you got a refund and the part was sent to you free? This sounds to me like PTP did try to correct this situation. But when I read the quotes of him saying never come back...blah, blah...it sounds ignorant.
To the OP....in this thread you come across very polite but somewhere along the line you rubbed John the wrong way. Maybe John was in a bad mood because his dog pissed on his rug, who knows.
I did think it was funny that he called you a "difficult" customer.

Sorry, a pretty big percentage of the people here use the SRT as a DD. We all want our parts as fast as possible.
