Cancelled my card. Every time I used it to charge at Total Rewards properties in Vegas, I was allowed to charge once. Every subsequent charge was denied. I had no balance on card & have had it for approx 3 yrs. Happened again this week. Called Comenity bank & they stated that everything was OK & that a block was put on on the charges because I was in Vegas. Now I go to Vegas 7-8 times per year, why does this continually happen ? Before I left this time, I called & told them I was going to be in Vegas & was assured by the rep that there would be no problem.
