The worst Provident fund investment

The experience with Bidvest Bank glasshock is pathetic. I have never see such terrible service. I recently got retrenched and bidvest is dealing with my provident fund. I had to change my banking details because of certain reasons and was supposed to get paid through the bank I initially had before changing my banking details however it bounced back so I let bidvest know and they accepted and said not problem they will change the banking details and I will get my funds. it's 2 weeks later and I haven't received anything. I call everyday to check what's happening with my payment and I've been getting promises that I will get the payment either on the night I call or the following morning. I've been dealing with Nadia which is the consultant and Ilze which is the manager I've been getting different stories I don't know what to believe anymore and it seems like I'm annoying them by calling everyday. Ilze and Nadia deal with the cullinan group that's why they assist me. I'm tired of calling and getting empty promises I want my money. I need Bidvest to do some thing as I really need that money because it's mine. Ilze even said to me that they just dealing with me and there's a lot of people who are on the list and got retrenched. who said I want special treatment? is it that hard to just change banking details on the system, and another issue is they've been telling me that it's the or system that's taking time, such lies! Ilze even told my HR that I'm rude just cause I would speak my mind and tell her that I want assistance and that I call everyday. Now if Bidvest doesn't do anything I'm going to even expose this on social media and tell people how bad your service is and that they should use bidvest
