Oyo Rooms — fooling the consumers.

I opted for a membership from oyo called wizard membership on 22nd sept 2018 on booking id jgqt3647, i was getting 10% discount as part of membership as i have opted a hotel as wizard base. Bt suddenly on 18th nov i was not getting 10% i was only getting 5% and after that every booking i got only 5% on 7 bookings (Booking ids are attached in ss).
So there is total of (126+108+95+152+46+168+138) = 833rs loss in total even after paying for membership i m not getting any discounts and i called them they say that there may be some technical error and dnt know the reason for this. Even after paying for membership i had to pay the extra amount.
