Metropolitan life insurance are opening ********** policies

it came to my attention that policy no.*** is being deducting R171 from my salary without my permission, and this deductions they have being happening from 01/05/2019 till to date, i called the service center to enquirer and they said i must do affidavit to confirm if i did not take this policy, and sent it to ***. i did sent everything(affidavit, ID, printout from persal to show the deductions on the 8th of June 2020, and they responded requesting my bank statement to refund me even today they have never paid me all my contributions, the policy it is active and i called the call center on many occasions and i could not get any help as they say i must sent email to *** as call center does not deal with such matter. what is frustrating me worse is that i never took this policy, i do not know details of this policy and metropolitan call center they cant even help on this matter. i find this as a *****.
