Charged multiple times

I was charged 6 times for one transaction. On another one, I was charged R259 first and then R323 the second time around. And then I was charged R64 four times for another transaction. This was all in the space of three days. That means R999 was taken from my account by Uber incorrectly. Money that I can't sit around and wait for. Money that I actually need now. I NEED MY MONEY PLACED BACK INTO MY ACCOUNT IMMEDIATELY!!!!
