Airtel Broadband
Oadband Connection not set up

I applied for a new airtel connection on 1st June. A guy came and collected my documents (id proof and rental agreement and cheque for Rs.899)

The cheque has been debited on 11th June but I haven't yet received the connection. I tried calling people who are supposed to set it up but nobody is responding. They initially picked up my calls and said that they will have it fixed but now nobody is even picking up my calls.

I need to get the connection as soon as possible or atleast get my money back.

Thanks
