Uber Won't Reverse Cancelled Charges

This is my last resort posting on Hello Peter as I have received zero response or assistance from Uber. I went to a music concert and when trying to place a request for an Uber, I was cancelled 5 times and charged for those 5 times to the value of over R1000. When contacting my Bank Virgin Money, they advised Uber had to reverse the charges. I have waited 10 business days as I was advised by email by Uber to wait for a few business days but nothing has happened. I am disgusted and disappointed that Uber seems not to care about taking people's money and I did rather enjoy the service until now. Please can someone from Uber resolve this as soon as possible and please do not tell me to wait any longer. Quite frankly, I believe I have been patient enough.
