Booking.com System Won’t Let Me Change My Room Price

I am managing the property “Apartment in Colombo Trizen Vistablu” on Booking.com, and I have been experiencing a persistent problem with changing my room rates. For a long time now, whenever I try to update my room rate from 75 USD to 62 USD, the system shows the new price only momentarily and then automatically reverts back to the old rate without any error message or explanation. Because of this, I am unable to set the price I want for my rooms, which directly affects my business. I also have no clear way to contact Booking.com Partner Support about this issue, so I have been stuck with the incorrect rate despite trying many times to change it. I request that this technical problem on my property be checked and fixed urgently so that my room rate can be permanently updated to 62 USD instead of 75 USD. In addition, I would like you to provide me with a clear and accessible contact channel for Partner Support so that I can reach your team directly if similar issues occur in the future.
