Oyo Rooms — automatic cancellation of my booking

I had booked hotel on 6-Jun-2019 with booking ID : TWFV3620
On 7th June 2019 midnight, I received a text message informing me that my booking has been cancelled.
I made a complaint on customer care but till date no resolution is provided.
I applied a special coupon of 65% discount which is also now used and i cant reuse it.
I have been given fake promises of either a call back or to hold line, but none of them have been fulfilled. Issues in OYO app is automatically resolved without the issue actually being resolved.
I received a fake email to rate conversation with guest experience manager, whereas i never had conversation with such personnel.
I also received message providing me extra 20% off but while applying it says that is only available for selected users.
I am seriously done with OYO. The way you manage your customers are very unprofessional.
Now i have been asked to rebook the hotel but at a current tariff which is higher then the price payable at the time of booking.
Why a customer bears the extra cost when the booking is cancelled from OYO's end due to some technical fault.
I want the same hotel for the same dates at the same price, otherwise i will make sure i never book again from OYO because of this experience.
Highly irritated customer.
