Hathway Cable & Datacom — hathway disconnection

Address:

560100

I have raised a disconnection request before three month, still i didnt get the disconnection, but everyday getting calls for offers. How many times i should raise request. How many times i should tell i dont want any offers but only disconnection. Hathway should respect customers complaint. They dont have proper portal to request for disconnection also. They want to sell it but doesnt want to take it back.
