Oyo Rooms — refund initiated but account not credited even after 2 months

A refund was initiated on 7th March 2020 against booking Id HCRX**** but it never got credited even after contacting them for atleast 30 times via email and phone call both.They keep on halting the process saying it's technical fault on their part.They ask for bank account pass sheet twice but at the end no response from their side.It seems OYO does the same with everyone, simply fooling people.
