Meru Cabs — no receipt of trip

Address:	Faridabad, Haryana, 121003
Website:	www.meru.in

I had taken a meru from the delhi t2 airport to faridabad on 15/12/2107 at 10:11 pm. They charged me a whopping inr 1217 and have not yet sent me the receipt for the same. I have sent atleast 6 requests so far and not even once have they sent it.
Even the otps also do not come.
It is the worst mobile app and service. I made a mistake once by hiring meru. Never ever will i ever take a meru.
