Unanswered Booking.com Price Match Claim Escalates for September Stay

After making a reservation via Booking for the dates of September 16–19, I submitted a price match request through the app because I found a lower price elsewhere. However, I received no response whatsoever to this request, and I am unable to reach anyone through the system or customer service.

My expectation is that my price match request be reviewed and my reservation updated according to the lower price I found, with my charge being reduced accordingly. I request that this lack of communication and unresponsiveness be resolved as soon as possible.
