Barclays PLC Credit Card Complaint

Barclays PLC Credit card department,

Billing disputes Pennsylvania

On - -, 2016 I contact the Barclaycard customer service as my payment from - - - was rejected and I was being charged service fees. I offered proof from - - that payment was sent and rejected. Customer service representative advised that charges would be reversed and at that time I paid outstanding balance in full. On my next statement the fees where still accessed along with extra interest charges. I again contacted their customer service on - -, 2016. This time they closed my account and were suppose to credit my account for about $44.00 in cash rewards. I paid my outstanding balance in full and Barclay has not credited my rewards cash and have continually assessed late fees and interest charges despite me disputing theses charges in writing to Barclay.
