Credit Card ABN AMRO — Dispute

Dear Sir/Madam,

Few years ago I used Abn Amro bank credit card. I made the payment in time but due to the bank mistake they credited my payment late. the result of this was that they charged me interest & late payment. but I had made the payment in time & that was not my fault & I sent many mails to bank to the bank but received no reply.
Then there collection guy started teasing me & to get rid of them I made the payment.
Now that was not my fault & even then I made the extra payment & the bank has given my name in cibel default list.
You can check I had a lot of card & I made all the payment accordingly.
Plz sir look into the matter.
Yours Truely
