Pending issues on my account.

This bank is the worst! Absolutely the worst! I booked a Uber trip on the 22 and 23rd and the trip were cancelled. Uber confirmed the authorisation hold has been voided and is pending on my account. Today I was charged twice for a trip and the same thing the amount was voided however it shows pending on my account. It’s been almost a week and R800 has left my account. I want to know where is my money why is it still pending and when will I get my money. I will be changing banks after this because a person can’t go on like this.
