Hathway Cable & Datacom — customer care call nuisance

Address:

Chennai, Tamil Nadu, 600101

I got a hathway connection from a person who promised me the rate of 750 pm and dual band wifi router and when i got that i only got a single band router which couldnt give wifi connectivity for more than 10 feet. Then when the plan got over i stopped using hathway. Because i was going abroad and didnt want to renew it. I though when i come back i will. But these people from billing customer care have been pestering me, not only creating nuisance and overall being rude. This is crossed more than 10 calls per day. Being a doctor when attending patients when these calls come its very irritating. It came to a point where its flat out mental harrassment. Since i have requested for disconnection from my side they have not processed that also. This is outrageous and lack of sympathy to the people they serve.
