Taxify is a *****

During December 2018 I was going home and I app**** the R250 promo. When i jumped off the cab the driver said I owe him cash R80. I told him I app**** the promo he said it did not reflect. I was forced to pay him this cash. Taxify is *******t. Today this morning (17 January 2019 at 6h20am) I had tried using a promo (R100 off) for a ride costing R55. It says insufficient funds. That’s mediocre. I have more than enough funds in my bank. Taxify are *****s! *****S I TELL YOU!!! Infact I’m deleting this app.
