Airtel — fraud in hotspot /broadband request

Address:	110070
Website:	Airtel

Hi, i asked for broadband and i got hotspot from mr. Dhiraj fron khanpur dealership centre. He sold the hotspot for 4000 approx and never started the connection saying verification failed. I asked him to return money or provide connection and he said there was no transaction of money. He took paytm payment in his airtel company number he said, cheque he refused so that the payment is instant and connection can be established next day. I denied cash payment due to recent demonitisation when i requested broadband nov 2016. Please help.
All i get is customer service agent returning my calls but no resolution as promised. One manager also spoke to me but he ended up selling broadband and did nothing to resolve hot spot issue
Are you delaying until the issue is too old and you will ask me to get lost then..?
Regards
