>I called David on the phone and asked why. He said I needed to fill out and return a LETTER OF INTELLECTUAL PROPERTY DESTRUCTION. Why he did not tell us this when we first asked for a refund I don't know. We promptly did this and again I did not think much about it until the following month when the credit still did not show up on our account.

This is an advantage to using a credit card. You have the power of the CC company behind you, since CC merchants must abide by certian rules.

Call your Credit Card company, tell them you are disputing the charge... they will ask for back up info... send them this message... I would print out any emails he sent you with FULL HEADERS... You have obviously made a good faith effort to get a refund from the vendor... The vendor said he would refund your money.

The credit card company will take the disputed amount off of your bill until they hear from the vendor... in this case, I am sure they will do a charge back to him and remove the charge from your bill.

You better hurry though, you generally have 90 days from the day you recieve the statement with the charges on it, to dispute it in writting. Sometimes you can make the date by notifying them by phone, then sending follow up paper work.

Good luck...

(BTW: I had similar bad experience with a vendor... technically it was my fault though, since I called 32 days after I purchased to product, and they had a 30 day moeny back. Even though I had sent emails prior to the 30 days, they claimed they never got them.)
