VERY POOR CUSTOMER SERVICE

good day I would like to express my deepest disappointment and disrespect regarding the service I have received from Old Mutual. I have surrended my early retirement fund with them, which I had to do on my birthday which was dated 15th Dec 2018. With my first paperwork they requested from me, I had not noticed the bank statement was old, and so did the consultant that helped me also not notice. I was then asked to return to the branch again to bring the latest statements so they could process the request, which I agreed to, since it was my mistake. I then went back to them on 21 Dec 2018 to rectify the mistake. they kept in touch with me by emailing me that it was received. I have been waiting and calling them after every week to find out about the process. I then left them to give them time. I then received a mail 2weeks back, to say that they just waiting for SARS to clear and it will take about 3 to 4 working days, which brings me to last week sometime. I then decided to call them today to check, since last week has passed by and still nothing was paid in. I was then told today AGAIN that the banking details were wrong and the money could not be paid in. I then stripped and became very angry, knowing I had to make another trip to them to go and rectify the very same mistake. The consultant that assisted me today was very friendly and helpful and mailed me the document to put my correct details and sign and send it back to her, and will then escalate it from there. My problem is that as a client I feel this has been just a mess up situation where nobody cares. If I did not check with them today, I would of just waited thinking I should give them more time, so who takes responsibility in this mess? I must be told to keep waiting for 48hours over and over again, we will escalate it, so how long am suppose to wait? after I have already waited so long? they just don't care an inch, as long as you are told to wait 48h or 72h, you must just shut up and follow their instructions, after I know I went al the way back to go and rectify what was needed from me. Why must I be treated in this way? I made sure I leave everything with them, including my payslip to see my banking details. please assist me in this matter since there is no respect from these people what so ever. I need that money ASAP. Please assist.
