Comenity review: Discontinued my jjill credit card

I have had a jjill credit card, and your connection to this store, for many years!
I had no idea that they were no longer sending a paper bill, therefore, I accumulated a balance of around $300.
I called jjill about this issue and they told me to reapply and that my credit card was revoked!
I tried to reappy online.
I recently received a letter saying that they were unable to approve my apllication.
This is absolutely ridiculous. I have a high credit score
And pay all my bills on time! I hope that you can intercede in my behalf so that my credit is not ruined.
