I also believe in giving second chances. I also have a very hard time with giving third, fourth, fifth chances... especially as someone who dealt with a similar issue a couple years ago. I worked out a deal on a new McIntosh amplifier using their trade up program with a local "dealer". Several calls, and much time later he still had not delivered the amplifier. A call to McIntosh showed that he never even ordered the amp.
American Express and McIntosh stepped in. A/E refunded my money and McIntosh arranged for a dealer in KC to deliver the amplifier to me (3-4 hours away), at McIntosh's expense. I later received a letter from an attorney stating that the state stepped in and he was forced to go out of business (I guess this must have become of common practice for him) and was working out some kind of method to reimburse those that he had defrauded.
Therefore, my trust level is low when I start hearing "stories" from any kind of sales associate, especially one dealing with expensive products. As someone who has always held the moto, "my word is my bond", I simply cannot tolerate liars, no matter what their excuses are.
