the worst experience with a bank ever

I came into some money and was advised thru Nedbank to see a financial adviser at the branch in Vangate Athlone for the entire time dealing with this person it has always been a struggle to get hold of him. Until Wed 25 October I decided I had had enough. I went into the branch and asked for a complete withdrawal over all the investment accounts handled byt the person in question. As he was not available one of (as I was told) the assistant managers assisted and I signed a single form. We then contacted from the branch the call centre to put the request into action. I was informed that all funds would be in my account on the following day. On the day I checked and found the monies was not adding up and inquired why this was the case, only to be informed that a second withdrawal request was only submitted on the 26th the day after I had signed at the branch. I then became very concerned as I struggled to get statements for these accounts . on further inquiry it came to light that the person introduced as the assistant manager together with the financial planner took it upon themselves to edit the original form I signed without my authority and submit it as a request from me .
