Dear [Recipients Name],

I purchased your discounted hamper last week as it was advertised at $69. Paying with my credit card, I have just received my latest bill that clearly shows that I have been charged $129 for the hamper. It is obvious that some error has occurred. The reference number for the transaction was 789-7657, which was billed to my card on June 9. I have attached copies of my credit card bill, as well as a copy of the advert. I believe that this is enough proof to convince you to make a refund for the difference in prices.

I thank you in advance for looking into and resolving my problem.
