Very unhappy with Old mutual at this point

I called their call centre to make a withdrawal on the 8th March on my Old Mutual Max Investment if not mistaken the following week I followed up and I was told that they could not pick it up on the system. They could only see the Feb one I then requested them to process that one and it was confirmed that I will get the money after 5 to 7 days which I did not. Then on the 20th I called yi cancel the policy forms were emailed and I filled the forms online the was I was told that I need to go to commissioner of oath which I failed to understand because when I took the policy I was not asked to go to the commissioner of oath. I am working from home hence doing everything telephonic and online which they must make things simpler for their customers. Then today the 27th March I get s notification that the same policy that I cancelled has been debited twice. I am very annoyed with Olx Mutual at this point and if I reverse this amount FNB will charge me. I just want that policy to be cancelled and have my money back.
