General Tires General Tire says largest retailer in the country's receipt is not proof of purchase. Fort Mill South Carolina

I purchased two sets of tires on-line from Walmart several weeks apart. I recieved the second purchase rebate from General Tire in a timely manner, but never the first. Upon inquiry into the first purchase rebate I was told by General via E Mail that the receipt I sent them did not have the purchase date on it. I circled the purchase date and re-sent the receipt. I was then told they require an actual cash register receipt " for auditing purposes ". The sender of the e mail stated if I were to send the actual register receipt she would " do her best to attach it to the claim, but could not make any guarantees " since the rebate expired two days earlier.I requested a phone number so as to speak with someone concerning the rebate, but have yet to receive one. The two receipts from Walmart that were sent to General Tire are of the exact same type, and yes the rebate I received was the lesser amout of the two.
