Paytm — Account blocked when I had amount in my account

Address:

Bangalore, Karnataka

I had booked bus tickets through paytm.com and due to some reason I cancelled it. I got mail from paytm saying your amount has been credited to your account but whenever I'm trying to login into my account I'm getting an error message saying " Your account is temporarily blocked". I tried to call to[protected] but its not getting connected I even rote mail to "[protected]@paytm.com" but there is no response. I want the account to be activated soon.
