HDFC Bank — My account is under restriction for no reason, either online payments can be received not done.

From last one week my hdfc bank current account is under restriction. I have Imperia account and still facing this issue. I am not able to check my account statement, unable to do any online payments, Neft from customers are getting declined. Can't even pay my hdfc credit card bill. Daily I am visiting branch, but they are clueless. They repeat same thing everyday that account will regularize in evening. They are not asking for any documents, no idea why account is blocked. UPI payments also not getting credited in my account. Suffering loss in business as its current cash credit limit account.
