I am being denied the promotion incentive for $20 on each tank of gas during a push they did to get cardholders to use their card more. I used the card a lot for little bit-more than was required to get the offer. At first they denied all my purchases-I think it was up to 3 or 4 tanks. After calling in to complain-I was told I didn't sign up for the offer. I not only signed up once in the first email, but I attempted to sign up twice when I got a second email a month later-and the screen said that I was ALREADY signed up. Months went by with no credits. So after the first call to WELLS FARGO who is actually the secret-ish provider of the card said no-I went to the executive offices to escalate my issue.They said 7-10 days to respond. Ok. I later get a person from the Executive Offices calling me to ask me what brands of gas stations are there in Texas? I couldn't believe it. Then he told me to just find the information and send it in. This was crazy-they had ALL of the information in my statements already. Long story short-the Executive Offices called today offering me just one of the $20 credits for gas.The person said-again-I didn't sign up to the original offer-when it was immediately sent.Then she said-I can only give you the one time $20 offer because you used grocery store or supercenter gas stations instead of independent gas stations. I never knew that was part of the deal. If it was then I am sure it is buried in 2 point birdseed light type somewhere. I used both. I asked for a copy of the original offer to be sent to me-she said she wasn't sure that Wells Fargo even kept copies of all the offers or not. I assured her that LEGALLY they have to. It's interesting that the only 2 times in 40 years of being a credit card carrier the only 2 problems I have ever had with promo offers are with WellsFargo. The woman that called also said that there were a lot people that had problems with this specific offer. That should tell you something!
