Hathway — wifi connection not done after taking the payment and misbehavior of staff

On 29th of june 2020 i have taken a wifi connection from hathway. I have made payment of rs 6372/- for a year. The guy named kapil told me that wiring for you connection will be done next and one day after that your connection of moderm will be done and your internet will me started. Next day wireman came he said i am short of wire i will come next day i said ok next day he came he misbehaved with my father as my father was telling him to bring certain tool so he can drill in the wall he said we wont do this if you want you can take your money so my father helped him do his work. Next day i called the man from whom i have take the connection he told me it will be done today but tht day he didnt do it i have called him 5 times a day next day also called him he said it will be done today but they didnt sent anyone to start or complete it. I talked to his senior he was not talking properly showing me attitude and talkin g arrangonatley. Today again i called but they are not replying. And my connection is still pending. One more person called me from their office and said drilling karni hai kya very roughly i said that work is done by my father. They are not replying when will it be done.
