What should I do in this case

Please help me in mentioned matter, as due to some medical problem I was unable to make the payment of my HDFC credit card for that every month I charged late payment, overdue fees and high interest on outstanding amount charged by HDFC bank. I requested Aditi (DVP at HDFC ) to convert my complete outstanding in easy monthly EMI so that i can pay my dues without any trouble and without hampering my treatment. I wrote so many email to HDFC regarding the same problem but I did not get any solution, Instead of solution I`m getting threaten calls for the collection guys that they will send police, and multiple people from HDFC visited at my residence address in my absence when my mom was alone at home and they asked my mom to pay the outstanding amount. At my home they have clicked some photos of my house and harassing me on daily basis on call and by visiting my address. But every time I told them that i do not have that much money so please convert in EMI I told them I am not denying for the payment. But no one is ready to help me. 28th of Nov I made the payment of 5300. And on this month I arranged some amount to pay the hdfc credit card bill and that amount got credited in my HDFC bank account, and when i access my account of make the payment of hdfc credit card I found that they blocked that amount in my bank account. On dated 8th of jan I called customer care for this concern they asked to arrange 16500 for payment of credit card as of now card status is temporary block as per HDFC customer care. On dated 9th of Jan I arranged 16500 and again called to HDFC customer care and I confirmed the card status, as per HDFC customer cared card is temporary block if i pay 16500 then It will be unblock and also release the hold on my HDFC bank account. With the confirmation of HDFC customer care I made the payment of 16500 on dated 9th of Jan and after 2 day I again called to HDFC customer care to know the status of unblock, they said that, they had suspended my card on dated 10th of Jan, and now not ready to reinstate.
