In 2008 I got behind in payments to Discover, and several other credit cards as well. I joined a program that lowered the interest to a reasonable 7.99 %. I paid on this account for a year, not missing any payments and the balance was going down and out of the blue.. they jacked the interest to 28.99%.
I called the compay and told them I thought I was in a program, and that is when I was told the program was for only a year and there was nothing they could do for me.
Needless to say, I got behind again, and they have been trying to convince me, that they are wanting to help me again.
