Standard bank -unacceptable service

Very disappointed with the poor service from Standard bank's client service call centre.Technical issues experienced at Standard bank on 1/12/21 resulted in incorrect reversals and my account a mess. All attempts to contact the bank resulted in dropped calls after chatting to 3 consultants, waiting period +90mins on my cel. The issue is still unresolved. Surely if a bank makes mistakes,recovery is important and Std bank dont care that their client is inconvenienced. The last consultant Keano advised that he is aware of the technical issues but cant help me. I must take it up with the technical dept and not phased that i waited 90 mins and counting due to the dropped calls prior to him. Shocking service !!!
