Booking.com account system is pathetic,

I have an establishment (***) linked to Booking.com. I have made payment on 15 September 2022 for commission owed to them. I have sent my proof of payment through numerous times, starting on 19 September 2022. I have made a mistake with my reference number on the proof of payment and I have been bringing it under their attention with each email that I have sent and the agents acknowledge that they are aware of it. I have phoned them 5 times already ( 27 September, 3, 10, 11 and 12 October) and the agents answering the call each time confirms that they did receive the proof of payment and they have been forwarding it to accounts, but my account still shows overdue and my establishment is not bookable. Meaning that because of Booking.com's lack of interest I have been losing bookings for a month already. This is really unacceptable. It is also impossible to talk to accounts people directly. I do not know how else to resolve this issue.
