Uber debited my account for no reason twice -unrecognized charges

I'm very disappointed at Uber South Africa. I have not taken a trip with them recently and yet on Monday morning at 10:50 I received two messages stating that my account has been debit for two separate amounts. They responded to me on email stating the below with no further feedback on this issue . So that means if you used the Uber app and paid with your card Uber cause debit your account as and when they feel and don't return your money even thou one did not use their services.

"We are sorry to hear that there is a charge you do not recognize on your account. Upon looking into this for you we were unable to locate the charges in question with the information you have provided."

This is honestly *****.
