Dishonest taxify Driver!!!! I want my money!

On the 25/12/20 my uncle came to visit, so he asked if I could request a taxify for him and he'll pay the cash, I requested the ride which was R230, about 20 minutes after he arrived, I noticed that I kept getting a notification that a transaction was declining, and that's when I realized that I forgot to change the payment option on my taxify to cash, I immediately told my uncle, but he said he paid the guy the money, I tried calling the driver and there was no answer, I then decided to send a message to the support team, after going back and forth, and telling me that they would investigate, 1 of the guys sent me a message saying that they spoke to the driver and that he said he didn't receive any cash (which was a lie) and I must contact him so he can confirm, they believed him straight away, he still gave me the banking details that I should pay the money to. I told this guy that the driver has been deliberately ignoring my calls, then when I tried calling again, the phone sounded like it's engaged or busy, straight after that I decided to put my number on private, and conveniently his phone rang, and when he answered and heard my voice, he dropped,... I told that guy from the support team what happened and that I want my money, and there's no way I'm paying another R230 to a *****! but now his not answering!, it's disgusting and scary that there are such sly and dishonest taxify drivers. I'm extremely irritated cause no1 is getting back to me and every time I get that notification from my bank for the declined transaction, I get charged for it.
