Unauthorized debits

I am writing on behalf of my friend regarding payments that goes off monthly . The bank statement shows no deductions. She went for an affidavit to proof at the office that she did not take any policies or loans. The monies went straight from her old age pension grant.She went to the office and she fiund out that a policy was taken out on her nane which she did not gave any permission and also do not have a contract for that matter. Sve is not tbe only one, because when she visited the office that day, there were also peolpe with the same problem
