Old Mutual *****

Last year May Old Mutual started deducting money from my salary without my consent, I've never had any policy with them and I wonder how they got hold of my persal. I went to complain but yet nothing has happened yet, they still continue to take my money and haven't stopped. This has caused me so much stress. I wrote an affidavit and submitted to them and it's almost a year now and nothing has happened. I need help.
