Tired of useless nedbank

Trying to cash out my forex from my travelcard. No branches open because of covid-19. Nedbank money app is useless!!! Don't be fooled by the "buy" or "sell" tabs, they dont work! Call centre says that it takes 3 working days to process and can't give me the rate of the day I app****. The customer continously lose money. We live in an era where tech should make things easier on the customer but the customers is forced (by the bank) to take the long route and lose money in the process. The worst place to bank at!
