Beware booking. com

I am very disappointed with booking.com. They advertised chalets for about R4900. When i reserved and went to pay, I was was told i will be paying about R7500. I queried the matter on a chat with Maohomed, and he told me to pay , and then he will deal with the matter and ended our chat. I have not received any reply since, and the next day the price on the chalets had gone up to R7200. BEWARE BOOKING. COM. I dealt with them for many years and never bothered to check, but i did feel that once i paid more than the original price, but ignored it.. Please be careful 🙏
