[Resolved]  Hathway — About harassment by Hathway customer care

I have been receiving calls from Hathway internet broadband services. I told them I was not staying at in Hyderabad (where the connection has been taken) due to work from home. I wanted them disconnect the connection also but instead of taking any action from their side, everyday I am receiving atleast 2-5 customer care calls either to recharge or other promotional offers. I have been explaining them my situation and they assure me they will update the database but agin it's the same. I have been blocking their numbers, activated DND even then I am receiving calls. Please help me with this kind of harrasment.
