Payment issue / blocked account

I see you guys don't like responding to your reviews... well I will take this further than hello Peter if I don't get a response within 3 days.

I used my promotional code for my ride yesterday got -R200 credit. When I was dropped off at home the driver asked me for R90. ***??? Firstly I've used a promotional code before and I have card details on my app as I know u can only use the code if you have the card option selected. So myself and the driver is going back and forth after realising there was an error, it first said invalid payment method then I closed the app and reopened it. Tried again and it worked. Meantime my payment option was changed to cash which I never wanted. I got in touch with a guy named Mohale. Most unhelpful asshole!

Here is my Order id: ********** 4 please feel free to read this idiots responses. Telling me "I understand the problem but you still need to contact the driver to find a way to pay him" and later said "The app automatically switched to cash because your card was invalid, what you should have done was report the card to us" How in Pete's name was I suppose to know the app was going to automatically change it to cash option? He admits the problem and tells me my account is blocked until I pay the driver.

I'm at a loss for words! I'm not going to pay the driver due to an app error.

Please get in touch with me asap before this gets out of hand. It seems I'm not the only one having this issue!!!
