Useless Company!

I had an awful experience with FNB; infact I'm very disgusted. I recently decided to open an account with them (about a month ago) so I have another bank account. But wow, I regret it. I requested a ride on Bolt (Taxify on Sunday 22 August 2021) using the card option. The ride was initially aupposed to be free of charge as I had a discount for R50 off if using card details. I entered my details and FNB reserved R100 for the bolt ride which was pretty much absurd. When the ride ended , it clearly showed on my emails ans on the Bolt app that the total cost for the ride is indeed R0.00, yet FNB hadnt reversed the R100 back. I let ot go since it was a Sunday, thiinking they'll reserve it back on Monday the 23rd of August automatically but still they didnt . I sent an email on the same day the 23rd with a filled in dispute form as per the process for them to reserve the money back into my account and they rep**** with a waiting period of 5 business working days. I waited but nothing. I sent another email to a different department but still nothing. It's been over two weeks now and still nothing. Telling me nonsense like systems are offline or "They're working with fewer consultants". Like how is that my problem? So it takes two damn weeks to reverse such a small amount back into my account yet when they reserved it, they were so quick to deduct it from my account. Im really ****ed and disgusted by the poor service they provided mxm. As soon as this is sorted out Im closing the account. It's pointless banking with such a useless company, sies!
