Consumer Redressal

I got Hathway Broadband connection last year. While taking connection they said me to pay Rs 1000 as installation charge and Rs 500 as security deposit. Even the sales person who came to provide connection took some extra money just because I didn’t had change and never came back. When I called Customer care,they said they don’t interact with Sales representative so they can’t give money back..Every other day some technical problem. If you want to talk to them and to register a complaint you have to pay atleast 10 Rs /call in reaching them and being on line. Some time back I disconnected my connection and when I asked them to refund my security deposit,they said they will send money back by cheque in 15 days,now it has been a month but they didn’t giev it back. I called them so many times,every time they just ask me my contact number and they said One of their team member will contact me in next 24 hrs but I never got a call from them. Please help me to get my money back.Thanks
