Bad attitude and poor service

I have a savings account with Old Mutual for the last 10 years and I am disgusted by the service I have received, I tried to withdraw some of my savings and have been given the run around, I receive automated emails constantly asking me for paperwork that I have already sent and I have to keep calling the call Centre only to be hanging on the line before anyone can answer. I eventually spoke to an agent and I really hope calls are recorded because her attitude is disgusting, I explained my situation to her but because it was almost home time for her, all I hit from her was her sighing on the phone from irritation and when I asked why is she breathing this way and if she doesn't want to assist me then I would like to speak to her manager , her response is that must she not breathe... All I want to do now is close my savings account which I had for the last 10 years because I am not receiving the best service and I must beg for what is rightfully mine... It's pathetic and disgusting and some one should teach these call Centre agents se phone etiquette!!!!
