Uber app a frustrating experience **********ly obtaining funds!!!

Absolutely worst experience using the Uber app prompts insisted for card details even though I was paying cash. It didn't make sense but nonetheless I knew the merchant (Uber app) or thought I did. The fee was R345.00. I paid the driver R370.00 cash which included R25.00 tip. I thereafter noticed a hold (R345.00) on my card, I went through the help guides on the app which noted that the hold is temporary and that the funds will be returned. To my surprise today I noticed the amount of R345.00 debited of my account. Absolutely disappointing experience with Uber. I escalated this query and am still waiting to be resolved.
