Very angry with Old mutual

I opened an investment the previous year with you. Had a stop order of R1500 and I was given a card but when I try to use the card it's not working. When i go to another branch am advised that I was not supposed to get that card. I was told that African bank sent a request to freeze my old mutual account but when I go to African bank am being told they know nothing about that. I did my investment with old mutual Vanderbijlpark branch and when I inquired about my money am being told they are running an investigation till today no solution. I am sent from pillar to post, old mutual is taking advantage of their clients because I know nothing about their investments, went to them as a trusted financial institution. But now they failed. If Old mutual cannot resolve my issue, I will have to lay a complaint with the ombudsman. And I want the interest that I was supposed to get while they are freezing my accounts . Can I also request the needs analysis I signed for the investment.
