I switched from a regular Shell credit card to the Shell/FuelRewards black card a year ago. Prior to that I had to swipe both my Shell card and Fuel Rewards card separately. So, in addition to offering a larger rebate, this was also a much simpler process. Boy, was I wrong. I immediately noticed I wasn't getting a lower price when I pumped my gas. So, I called Shell (I think) and was told the credits on that card would appear on my billing statement, which is handled by Citibank. Wrong. No billing credit. I called Shell and they bounced me to Citibank, saying it was their problem. Citi bounced me back to Shell, etc. After nine months of follow the bouncing ball, I finally spoke with a Citi rep who said it was indeed Citi that needed to activate (link) the Fuel Rewards to the card and he would take care of it immediately. On my next bill, I finally received a bill credit, but as it turns out, it was only for the prior months. It still was not linked to my card. Fast forward to last Friday, when I again received my bill with no credits. Spent a total of 3 hours on one phone call, getting transferred back and forth between Citi and Shell. Finally got a supervisor at Citi who said he understood the problem and would definitely be able to take care of it for me. Before I could say BOO, a lady answered with, Hi, I'm Monica. How may I help you?" After questioning, turns out she was with FuelRewards, which is a third corporation, completely separate from either Citi or Shell. They are Excentus Corporation out of Texas. She tried to bounce me back to Citi, saying it was all their fault. I protested and informed her to coordinate between Excentus Corporation, Citi and Shell to get the problem solved between them, as I had already spent tens and tens of hours to no avail. She agreed and said I would get either an email or phone call in the coming days to let me know it had been fixed. I supplied her with ALL my account info. Two hours later, I began receiving emails from Excentus Corporation (apparently via Salesforce???) wanting me to supply the info that I had already given, Each time I did, I would receive another automated email from Excentus Corporation with a new trouble ticket number. With each new ticket number, I would then, a couple of hours later, get an email from another rep requesting the same info I had provided to all the previous reps. When I reply, I get another automated email with a new case number and a new rep. Yes, that was exhausting! After a year, I am canceling my accounts with all 3 corps and will be filing Federal and State complaints for deceptive billing practices and buying my gas at Chevron. Unless you want to waste a year and end up with nothing but aggravation, don't bother with this SCAM.
