Double & Triple charged repeatedly with no refund

I am so angry. UberEats has ****** R256.00, R329.00 and R108.00 from me (R685.00 in total). I was double, or tripled charged on the three occasions and the money was NEVER returned to my account as promised. I will never use this service again and am making it my mission to let everyone I speak to know that they shouldn't either.
