Abn Amro — Credit Card Closed in Year 2015 paying Full amount, CIBIL Score is impacted Negative

Address:

Hyderabad

I had a credit card of ABN AMRO in year 2003 and closed it clearing all due's in year 2015. As per the process I closed the card by visiting the Banjara Hills Office, Paid the Due amount, Cut the card to two part's, I have put it in the envelope and Dropped in the Drop Box. I discussed with the Official's there and they said all the process is done and your CreditCard is closed successfully. I took two days off from office to do so in my busiest schedule at that time.
After a month I got a bill amount of 300+ again. I am very unhappy and was not interested to further pursue as they were busy day's and getting a leave was difficult. Later after few year's this amount if grown to 7000+ Rs and getting reflected now in CIBIL with status Written-Off.
I sincerely request you to Pursue this issue and do the needful.
