Deceased Members Refund

I am an employee for DSV, and have been a member for Safrican since 2014, my membership number is ***, so they deduct directly from my salary. Honestly all was going well, until this year. In June I lost my grandmother, early July I submitted a claim and I had no issues at all with safrican they paid me, end of July when I got my payslip, safrican had deducted fee of R84 for my late grandmother, I then sent an email on the on the 28-07-2022 asking how does it work with removal of the deceased, they responded on the 29-07-2022 and told me that system automatically removes the deceased. In August I lost my father whom was also part of the member I was paying for an amount of R33, end of August the same thing happened safrican deducted for both deceased members. I followed up with them asking why was there a deductions for the deceased members if I was told that their system automatically removes deceased members, they sent me an updated certificate, End of September when I got my payslip safrican had deducted again for both the deceased members. A week ago I followed up with them they said the were waiting for HR, yesterday I followed up, they responded saying my HR should be the one to refund me. Why should I fight with my HR if they are the ones who took the full premiums if they are the same ones whom advised me that their system removes deceased members automatically?
