Hathway Cable & Datacom — broadband connection disconnected even after payment

I am one highly frustrated Hathway customer in Pune.

My account was due for payment on 4th Oct, and i made a payment on 29th Sept (5 days prior to expiry). For some unknown reason this payment was not recorded in Hathway. They disconnected the connection on 5th.
Since then i have been following everyday, sometimes even more than once. Everytime i reach CUSTOMER CARE and they keep giving me ###, ask the same set of details on how the transaction was made. Everytime they mention that the problem will be resolved in 24 hrs, and i have been waiting for last 8 days since this payment was made to get the connection rectified.

I don't know whom to contact or how to escalate to get the problem rectified.
