Pathetic service - no service

I am so appauled with the pathetic service i have recieved from Old Mutual. I have been trying to simply cancel my RA from December. Till date the number I was given to call just rings for days on end. I then went on to email my request, and submitted all the necessary documents, only to find random agents replying that they are busy ( doing nothing) and that in order to process my application i must send it writing which i keep explaining I have sent it its in the attachment. Clearly I am not a valid customer. I should have been assigned a case number and ONE agent to process my application. But inefficiency is the case here. I can't believe i have trusted Old Mutual with my investment. They are a no show. You can't even contact them. I am shocked. I want to cut all ties with them! But even that is like impossible to do. They were all over me hunting me down in the workplace for the sale, but now when i really require some advice and assistance due to immigration which i have already explained to Rene Nadasen when she insisted on still signing me up. I better hear a proper response from somebody soon.
