Poor Service - Capitec Bank

Two weeks ago I contacted my bank regarding a holding deposit that for a car rental after I was advised by Avis to follow up with them. A consultant named Minolan spent over 40 minutes trying to assist me and at the end resolved that I forward him the document from Avis which I did whilst on the line and he confirmed receiving it, Two later and numerous emails and calls to be bank I am still waiting for feedback and the bank to release the funds but everytime I call the call centre I have to explain the same issue. I am really losing my trust with the service as I will be using a more car rental services in future but this exprience has taught me not to use my Capitec Bank cards anymore.

I am following up again on the reference ***0 and today I was told that I will be contacted back but to date there's no feedback.
