Smartmart Savers Gas Rewards Scam involving gas rebates Lake Havasu, Arizona

Was given a rebate certificate for $300 in gas rewards as a "thanks" for attending a sales presentation for a travel company. Followed all the directions to get the rebate certificates including sending them in using certified mail. The first was sent Thursday, 8/25/11. Received the $25 monthly rebate check and next certificate. Sent this one by certified mail 30 days later on Friday, 9/24/11. When my check did not come for some time, contacted customer service on 10/12/11 and was told I didn't get it because they RECEIVED my rebate in less than 30 days. Due to the weekend, they are claiming the first rebate was received in 5 days and the second was received in 3 days, therefore making me ineligible because they received it in less than 30 days and canceling the remainder of the $300 rebate. No where in their paperwork does it say 30 days between the rebates being RECEIVED. The paperwork says that only one coupon may be redeemed within a 30-day period. I have proof via the certified mail receipts that I SENT the second rebate 30 days apart.

This is a flat out scam. Who has control of the mail? All I know is I sent it 30 days later. Was told a supervisor would contact me in 24 - 48 hours. On 10/17/11, I called again since no one called me back. Was again told I would get a call back. Finally got a call back and was told because they RECEIVED my 2nd rebate with less than 30 days between, I was not null and void and would get no further rebates. I again stated that I had the certified receipts showing that I had sent them 30 days apart to which Jennifer replied "you are null and void because we received them in less than 30 days apart". I perceived her to be very curt and rude in her tone.  Shame on any gas stations who participate with this company
