Double charging

I am very upset, angry and disappointed. On Saturday 26.09.2020 I requested a ride for my parents and paid for the ride via EFT, next the the driver takes R300 from them. I contacted Bolt services and they advised that the need to investigate, It is Saturday again and I still waiting.... I contacted Linda the driver and asked why is he double charged me he said he reversed my Eft payment, he then promised to repay me the cash. No payment received from him. His phones are off now, I am just wondering to how many other people he is doing this. I told him I want me cash back. I am skeptical to ever request rides from the Bolt service.
