Appalling service by Hollard

Hollard (life wise) has been deducting R100 from my persal, i started noticing last year October. I reported the matter at a branch in Pietermaritzburg, they requested bank statements, payslip and affidavit to lodge an investigation. I went back twice after that, but the issue still hasn't been fixed. I have never been approached by a Hollard agent so i don't know how they got hold of my details
