Help me surrender my anuity staff unco-operative I cannot speak directly to the person.

Good day My name is Johannes Smal ID ***. I was treated very stifly in the Meyerton branch after telling them that I had to get assistance from Hello Peter to finally change details to... after 20 months of trying to change the payment from ABSA to Old Mutual account. I have now app**** to surrender the anuity but I have been told that I cannot do this. I was told not to bother the branch for at least 15 days. Now they have said that I cannot surrender the anuity. Please who can I speak to in this regard I really need the money and I am left at the mercy of staff more intrested in sending me home saying that I must go to a relevant branch or they are so busy with their lunch. I just need the money from my anuity. Can you please assist me in this matter. No matter when I approach the branch either they are offline or no one can help me. We have tried the Alberton branch with no luck either. Please Old Mutual I am a senior citizen who needs assistance. Blessings and I have faith that you will be able to assist me on this simple matter.
