disgusting and pathetic service

I'm really at a point of being frustrated with this company to a point where I feel if I have to struggle this much for banking details to be updated what more when I need to claim from my investments. I have been calling old mutual for the past 3months for banking details update after reactivation of an account they had closed without my knowledge and now they are dragging to update my banking details then soon I will find that I'm in arrears because of their incompetence. i am more than ****ed , having to beg a company to take my money seems pretty pathetic and at this point I'm considering taking my investments elsewhere
