Dismal service from Standard Bank

Standard Bank Carddivision loves paying russian roulette with my card. Last week they blocked my card without notification, refusing a R200 fuel purchase, which resulted in me having to walk home and spend 40 minutes on the phone to them, then walk back the 2km trip in the blazing sun. Today, I am trying to pay for a workshop and they blocked the transaction again. After 30 minutes dealing with a directionless IVR that sent me to vehicle finance and transactional banking, I was finally put through to some Bafana in *****, who said they would remove the block and I must try again (apologies are not part of the customer experience). Well 3 tries later and no joy. I am currently 19 minutes into a call to Private banking who are experiencing "High call volumes". This is a failed bank. I doubt they will be around in 2030
