Barclays PLC Credit Card Complaint

Barclays PLC Credit card department,

Late fee Connecticut

Barclaycard does not credit - online payments when they are received. For a year prior to -/-/2016, all my payments were credited when received. Since -/-/2016, Barclays has not credited the payments until days after receipt, which generates interest and late charges on top of interest and late charges. ( Please note that I always pay-off the entire balance every month. ) I have written twice, phoned 3 times, had three ( 3 ) separate email conversations with customer service and sent the required copies of Peoples payment details evidencing on time payments. Some fees were credited then reinstated. My overpayment on -/-/2016 is not considered by them to be an overpayment. Their latest claim is that they have never received the Peoples evidence for -/-/2016, yet they acknowledge they received my second -/-/2016 letter containing that evidence. I have over - hard copy pages of documentation to prove I do n't owe them any late fees or interest but their customer service will not give me the name of a supervisor or look at the account in totality back to -/-/-. I have a letter from Barclays stating that the matter was resolved and all fees rebated, but that is not the reality per their customer service. The credit card Customer service is impossible to deal with.
