My worst experience with booking with booking.com

On the 20th of Jan i booked a guest house in Port Elizabeth via bookings.com. I had to pay the booking fee upfront with no cancellation refund and that was fine with me because the booking amount was within my budget. The most frustrating thing is when i got there i was given another invoice and i was told the booking fee i paid was a mistake "the website i used advertised the incorrect amount" according to them. The worst part is when arrived there it was around 20:00 a night in a strange city with this pandemic (COVID). I couldn't cancel the booking and the it was not easy find a new place at time because of the curfew times ending at 21:00. I very disappointed at booking.com because I ended up paying R1900.00 more instead of the R382.00 that they said i will pay for the booking. It was a inconvenience for me because if i knew in time i would have looked for another place that is cheaper.
