Worst service and I'll treatment of the Senior citizen

My Father had an investment with Stanlib for a very long time and 2 weeks ago he went to withdraw and all paperwork was submitted by his financial adviser. Two weeks down the line he has been sent pillar to post. I have even advised him to go to nearest standard bank but he could not get a straight answer. I helped him to call and it was suggested that he must go to nearest standard bank for authentication but we disputed it because he was just at the bank but didn't get a straight answer. We were then told the supervisor will call but that did not happen. When we phoned following day it was another different story.
