What is the service experience of OYO Hotel?

Oyo is really too pit, don't live there. I booked a hotel on it, but when I arrived at the hotel, I told me that the room was full, and I never cooperated with oyo again. Then it passed 18, and there was no refund. The customer service phone kept telling me that it had been fed back, and the supervisor took half an hour to deal with it. As a result, I waited all day without responding. What a pit. In fact, many hotels on oyo have cancelled their contracts.
