Wesbank has a zero service policy

I have been waiting for a refund of R452 for duplicate Registration certificate for a vehicle since December 2022. I have made so many phone calls that I guess I've spent more on the telephone bill than the refund due. I call into Wesbank listen to so much music, intructions... eventually a consultant answers my call, I ask to speak to the team leader whom has supposedly been helping me. I hold on for ages sometimes I'm fortunate enough to speak to this team leader who promises to sort the refund out, but to date no refund has appeared in our bank account. The last call to the team leader last week I was told the refund was authorized and the funds should appear in our bank account within about 48 hours, nothing happened, no refund. Today I emailed this team leader again. But no reply to my email. This seems to be standard practice with the team leaders. I called and asked to be put through to the team leader who has been "assisting " me. He did not answer his phone and the call center lady said she would send him an email with a message that he should call me. As usual nothing, no response. No reply to my untemth email and no call back either. I'm so frustrated and disgusted with Wesbank I don't know what to do!! NOT EVEN BAD SERVICE. THIS IS UNNECESSARY AND NO SERVICE!! WESBANK YOU ARE A DISGRACE !!
