Booking.com is a ****

On the 22nd of July, 2025, I hired a car from Alamo in Durban, through booking.com. I paid a deposit of just over R4000. I'm based in Cape Town and was supposed to pick up the vehicle on Thursday night, the 24th, when I landed in Durban, Alamo didn't give me the car as I don't have a credit card, even after explaining that I had booked with my business card, as I was on a business trip, everything had to go through the business account for accounting purposes. I still didn't get the car and had to use Uber. The next day I contacted booking.com and explained what had happened. They apologized for my experience and told me that I would get a full refund within 5 days. It's been over a month and I still have not received my money. The last time I contacted them through their chat system, they told me that Alamo had not responded to their emails, asking them to confirm whether I had received the car or not. I asked why couldn't they just call them and they said the number was not going through. I immediately googled Alamo, called them and went through without any issues. I went back to the chat and told them that I had reached Alamo and gave them the number to call. They told me to hold while they tried to call the number I had given them. They came back and said the number I had given them was also not going through. I called the number again on my other phone and went through without any issues. That's when I realized that the booking.com people were playing games with me all along and that they did not intend on giving me back my money. I've got screenshots of my interactions with them, please assist.
