Booking.com Bad Service

We booked and paid to stay at Umhlanga Cabanas in Umhlanga and travelled to the holiday resort and we had checked in and was settling in at the apartment that we booked. whilst settling in we were telephoned from reception to say that we need to vacate the premises immediately and come down to reception and give them back the keys as the booking has been cancelled and they advised that they cannot assist any further. We had to leave and travel back home on the same day . My husband only checked his email a day later and this was the email : Important update: Reservation *** at Umhlanga Cabanas Hi ***X,

Unfortunately, Umhlanga Cabanas informed us that they can no longer accommodate you due to overbooking. To keep your trip on track, we've found you a similar place to stay:

Link: https://www.booking.com/59acd038730ca Name: Harcourt Lodge Phone number: +***4 Address: 78 Musgrave Road 1, Musgrave, 4001

This was very alarming- we were already in Umhlanga when this email was sent. No one tried to call us and Musgrave is not 1 mile away but a whole city away and not near any holiday areas . We had booked and paid on 14 Jan 2022 and only received the refund back on 21 Jan 2022. Poor service .
