Uber support is useless

I took a trip on 11 March. Uber took R 120 hold and then debited me again R 155 for the trip. I was invoiced twice for the same trip. They have not reversed the R 120 hold and now are not responding further to my emails. They did say they would credit me with R 35. (For what?) I haven't received that either. I was an Uber driver for 7 years. Their support is sadly lacking in eptitude. I suppose that is because I'm talking t9 a computer not a person.
