Rude Customer Care Experience

I closed my Barclays credit card account last year, and yet they continue to charge me an annual fee that I did not pay which caused my credit score to go down. I never got a single bill. I went to solve this issue at their branch and I connected with one of the customer care executives, his name was Mark, he didn’t listen to my concern and told me I can’t help you in this case. I asked him to meet your branch manager after reminding him so many times I got to meet him. He said that we will resolve your issue but it will take time. Spend long hours just to clear one issue and that too was not solved first hand. Still have to wait for their reply.
