I also had problems creating an account for the Comenity Bank website. You have to type in the store name to be directed properly and nothing came up when I typed Total Rewards.
So, I left a comment stating I didn't know how to log on. Of course, I received the message they would respond during business hours. Well, wouldn't you believe it, they emailed me back about an hour later with the link. (It's comenity.net/TotalRewardsVisa for those who are interested)
I've already logged on, made a payment since I've already made a charge to get my rewards points but want to keep it at zero as much as possible. It's true I didn't see an auto-payment, but that doesn't both me much.
We'll continue to follow what happens...
