Right Size Smoothies wanted a return autorization code - was convinced to take a 25% discount - decided again to get an autorization code - was refused because I accepted the 25% discount. Internet

My husband ordered 3 canister of Right Size Smoothies for a total of $147.26 on the telephone.  We received the canisters on Saturday 10/1/11.  My husband tried the vanilla twice - both times it did not agree with him.  His heart rate went up.  We decided we didn't want the canisters.  I called Monday 10/3/11 and was convinced to take the canisters at a 25% discount and maybe I could sell them.  I agreed to a statement saying the account is concluded.  I then talked to my husband and he ABSOLUTELY does not want the products.  When I called back , Right Size said that I agreed to keep the product.  Can you help??
