Delhi Police — company cheated of service

Address:

New Delhi, Delhi, 110008

I am a resident of 15a/18, east patel nagar, new delhi-110008

We contacted a company micra elevators and paid rs 36000/- including gst towards annual maintenance contract on sep 2018.

Mr sanjay came to our house and took the money and handed over the contract.

After that we had developed some problem in the lift so we tried to contact you. He became inaccessible. He had given us following numbers :-
1. [protected]
2. [protected]
3.[protected]
Out of the above number, one number comes switch off always and the other is picked up by some mr arvind and he says that he was working in that company but has left the company
3rd number is being picked up by mr sanjay's wife
His wife is available on[protected] but she doesn't make us speak to mr sanjay.
The address in the invoice is :
Micra elevators
76, raja ram market
Madangir, new delhi

He has cheated us of rs 36000/- and must be cheating many.
Please help
