[Resolved]  HDFC Bank — Put me in defaulter list

Address:

Surat, Gujarat, 395007

Around 4 years ago i was late with the payment and i got charged with around 500rs. when i called the call center then he told me that company will reimburse my charges, which didn't happen and i stopped using the card. last year i applied for credit card at standard charted bank, my application was rejected because i was defaulted in hdfc card payment. i contacted hdfc bank and paid the full amount which was now 5000rs. i didn't settle but paid the full amount due. hdfc bank gave me no due certificate and told me that my cibil will be cleared within 3 months. its now 7 months so i applied for a card and got rejected again because i was still in the defaulter list in hdfc bank.
i also applied for a card in hdfc bank just to see if they actually have cleared my account and they also rejected which proves i am still at the defaulter list in the bank.
then i contacted the bank and told them whole story and they told me that they will issue the card but today i got the mail that they can't issue because my cibil is not up to the mark.
how the hell my cibil will be cleared as you have ruined it. i don't care about the hdfc bank credit card all i want them to clear my credit history.
i don't know what to do as i already have paid full amount what else i can do.
