Unable to Contact Apartment Owner in Poland – No Support from Booking

We rented an apartment in Poland but haven’t been able to reach the owner. To make matters worse, we also can’t get in touch with Booking.com. It’s frustrating that a global company like Booking is unreachable when problems arise, even though they have no issues collecting payments. We urgently need Booking to help us contact their partner in Poland. This lack of support is unacceptable, and I expect immediate assistance in resolving this issue.
