Old mutual policy without my knowledge and no refund made

Old Mutual South Africa...apparently one of their representatives opened a policy on my name without my knowledge. I have never even requested a quotation from them, that person has my identity number, employee number, my mothers name but the address and contact numbers are not ours on the policy details. I noticed in September 2019 when on my payslip and went to the Cape Town Adderly street branch. They were suppose to investigate the case, cancel the policy and refund me. I did the refund request and i was refunded for the month of September however the policy deducted again in O ctober and November 2018 and policy was not cancelled. Went to the same branch on Wednesday last week for refund and cancel the policy, they said the refund takes 5 days. Its been 6 days and I have not been refunded nor have they concluded the investigation. I was considering savings for my childs education but after this experience I dont want anything to do with them. I am sure they will deduct in December again. So so so ****ed off
