HDFC Bank — Credit card blocked, no support from hdfc support team

I have reached out to the hdfc care Twitter account since I am.not in India and am travelling from Ukraine. I specified my situation to the support and told him that my card is blocked and I need it since it is an emergency. I also made the due payment and yet I can't do anything with my credit card online or on atm. I am able to make changes smoothly with my debit card. I am sure they have blocked my card since I haven't used it for over 3 months and they made me wait over 4 hours to tell me please call the bank on a number they provided. Even though after specifying my situation of not being able to call the bank, thus reaching out online. They came with that response after 4 hours, that is how HDFC listens to customers issues and complaints, by not listening. I keep getting : This transaction is currently not available for your account. All the time. Very very disappointed.
