Stanlib Cheating their clients

I have been a loyal customer of STANLIB for the last 20 years and recently I decided to review my portfolio and the costs. After reviewing this information on their online portal I quickly realised that they have been charging me fees for which I am not liable e.g. advice fees as I have never ever had a advisor. I immediately contacted them and advised them accordingly and requested a statement on all my accounts as I no longer trust the institute. The matter was then escalated to their retention team and they advised that there seems to be issues with my account and they had invested me into the wrong account. This further concerned me as to the fact that this organisation does not really know what they are doing. For any individual this is extremely concerning as we are being cheated from our hard earned money and after working for many years when we will end up with no funds when we need it. I advised the consultant that I wanted all the incorrect fees to be paid back to me and to provide me with a full statement of the account. I was advised that Stanlib is not willing to do that and that all they can do is to move me to the correct account now and start fresh. This is ridiculous and I advised him that I do not accept this and want this matter escalated. This entire issue started over one month ago and I am still waiting for a senior representative from Stanlib to provide me with my statements and a solution to the issue. It has been impossible to deal with such an unprofessional organisation who are cheating their clients and not willing to fix their mistakes. I can only advise people to look at their accounts properly as such organisations are cheating many people out of their hard earned money and I am sure I am not the only one.
