Appaulling service

I opened an investment account a few years ago and I struggle everytime I need to withdraw my money. I had the same issue 2 years ago. I have been trying to withdraw for over a year now, since last September. I was made to fill a form and send it back, that was done but I still don't have access to my money. I have been calling for over a week now and the agents keep hanging up on me saying they have system issues. I jusy spoke to Shantel who was very rude and even asked me what must she do if she can't access the system? I want all my money, then you can cancel your stupid account.
