Nedbank's Service in decline

Nedbank Credit Cards perform very poorly online often declining. I make a monthly payment to the same vendor but in the past 2months this payment is not possible because Nedbank's system is broken. I've followed up with the vendor and Visa and Nedbank techical. All fingers go the same way - Nedbank's processing server has glitches that Nedbank has failed to solve for 60days running. It takes oodles of interactions to get anything done. Interaction counts are 20 on this issue alone and resolution is not nearly in sight. And after reporting the issue again this week I got a call from the Nedbank call center where the only thing the agent said was "I'm pleased that this is now resolved" Then he hung up on me. I don't know what kind of games Nedbank plays!? Nedbank takes 3-6months to resolve any issue. Branches are slow with staff sitting on the phone on social calls instead of helping me in my previous visit. Nedbank's service is spiralling in the past at least the staff where friendly and knowledgable. Now we have poor staff and poor systems combined. Next step -> Find a New Bank.
