Terrible service from Wesbank

I made a settlement payment on my vehicle on the 12th of August, I phone to ask if they have received the money they said no but I must please email them the proof of payment which I have done. I received a email back to say that someone will contact me within 24 hours.... It has been a week and not 1 person has phoned me not 1. I have spoken to a couple of people at wesbank and they all promise me the world that somebody will phone me back on that same day end of business and nobody ever phones me back I must always phone them. This is terrible I have never in my life had such bad service from wesbank. I just got of the phone again with wesbank now they tell me I must go to the bank. Surely in all my calls somebody could have told me to do this in the first place instead of lying to me and telling me that someone will sort it out and contact me. I am very disappointed!!! And you know what.... if it was the other way around that I owed them money they would have phoned me at least 100 times by now. It is disgusting.
