Barclays PLC Credit Card Complaint

Barclays PLC Credit card department,

Closing/Cancelling account Nevada

I have recently had some credit card delinquency, but not with some of my banks that I currently have revolving credit with. I have been trying to resolve my financial issues. In the meantime, I have never been late with a payment or delinquent with my Juniper Card through Barclay. I received my tax return and paid $1000.00 payment on my Juniper card because I will have to take a trip -/-/- and reserved a hotel room with it. I checked on my account today online to find my account has been closed! I called the number for customer service, thinking it must be a mistake because my card does not expire until -/-/-, and customer service informed me that my account has been closed due to my credit report. Can they steal my money that way? Can I sue them for corrupt practices? Where is my consumer protection?
