Dear Name of Contact Person:

This letter is to complain about a remote control dinosaur that I bought on DATE, at LOCATION. 

I am requesting that you replace the toy with a new one as my child likes it very much and would be disappointed if it didn’t work properly. Otherwise, I would like my money back.

I paid with a VISA credit card and have enclosed copies of the receipt, credit card bill and warranty card with this letter. 

The toy worked well for two weeks and has stopped working. I changed the batteries and took it back to the seller, but he said there was nothing he could do. The warranty for the toy is for one year.

I look forward to your positive reply and will wait until DATE before seeking further assistance. 

I can be reached at Email Address or at Phone Number at any time during working hours. Thank you in advance for your quick attention to this matter.
