Taxify "trief"

I sent a complaint to Taxify 28 July 2018 regarding a driver. The driver picked me up at Bob's District 6, started the trip then went to the garage. When we were at the garage he went across the road, peed and smoked a cigarette before actually starting our trip. This resulted in a R170 trip being R235. I sent 2 complaints through to Taxify, the first was for the driver canceling and I got a response within 1 day apologizing which I accepted. However, the one requesting a refund for the difference of the trip I had with Robert seems to have even ignored. I feel like this is horrible as, comparing to Uber, when the driver needs to go to the garage, he doesn't start the trip until he's done at the garage and on the route to the destination. Please help me address this with Taxify and have my refund back.
