Poor customer service with issues

I cancelled 3 trips. 2 of which was on the same day at a big sporting event. The pick up location was far from where I was so I cancelled untill I got a driver that collected me where I was. I paid the R25 cancellation fee for both, but the authorisation hold has been on my account for almost a month. Third trip I cancelled because the driver was 25 minutes away. The three trips amount to R1282, which I now cannot spend this festive season. I Emailed uber, they said I should take it up with my bank as the amounts were voided on their side. Went to my bank, they said uber should cancel the holds, I cannot do it myself.

Phoned Uber, got a repeatative rehersed answer that I should take it up with my bank. I cannot understand why I should pay a cancellation fee and then the reaponsibility lies with me to get my money back!! The call centre agent says Uber does not know what the bank's policy is. How is this possible!!!!???? Do you not check the policy and procedure of banks in the countries you launch the app?
