Incompetence - Processing Team, Maureen & Andre

I requested a partial disinvestment on my funds. After fulfilling umpteen documentary requirements (apparently Regulatory Requirements) and waiting weeks for my money to be paid out, I received an amount missing one zero at the end of the figure. I was basically paid one tenth of what I clearly stipulated on my documents. Calling in to Old Mutual I spoke to Maureen who acknowledged that there was an error. She then consulted Andre (a coach or back office resource) and said they would provide me with feedback the same afternoon or the next morning. This never happened. I called in again and spoke to Bladley who consulted Maureen/Andre to tell me that I can expect payment of the balance by the end of the week. He also informed me that he would be notifying his manager in order to address the failings. There was no call back to me as promised to keep me informed. Most shocking is that there was a processing error of this nature and that I now have to wait even longer for my money. Absolutely unacceptable turnaround time. I'm contacting other Financial Providers to find someone who values my business, has a shorter turnaround time than 3 weeks and who's able to process my requests correctly. Doesn't seem like a lot to ask for, does it?
