Hathway Cable & Datacom — hathway torture after broadband disconnection

Fed up beyond limits, because of the no. Of calls, i receive from hathway customer care.
I used to hold a hathway account about 6 months back. But i shifted my connection to a different service provider and handed over the device. So now i have nothing to do with hathway. But the calls are unstoppable! I have informed the customer care and have been patiently telling all executives to delete my no. From their calling list, but they continuously call and which is very frustrating.
