Barclays PLC Credit Card Complaint

Barclays PLC Credit card department,

Customer service / Customer relations California

I have had a card relationship with Barclays for years. I went to use my - - rewards card today and it was declined. When I called in I was told all of my card accounts were closed and would not be reopened. I would like my account reopened as I have done nothing to cause my account to be closed. I 've always paid my bills on time and hardly purchase anything on it, I never let the spending be higher than I can afford to pay monthly. My credit history and score are very important to me. Please contact me via email or through CFPB. Again, anything that can be done to preserve my relationship with Barclays I would greatly appreciate.
