Worst / horror service so pathetic

I joined Sizwe medica fund in June 2018, and for June, July and August 2018 they did not deduct the monthly subscription as per the agreement. Howevever in month September 2018 they deducted for 3 months I mentioned above and for in October they deducted for Month September and October 2018. When I contact their call centre I am being told that the money is not appearing in their system hence I have a proof in my pay showing deduction of all the monies. Worst of all I have received an sms today saying that my membership has been suspended due to non-payments.

I would like to find out how is it like that because the payslip reflects that the payment went through. I am not even getting the necessary help from their call centre agents.
