DirectAxis - non-existent claim department service

I was retrenched on 8 May 2020. I have VAP Premium Group Life cover which covers my personal loan installment for 6 months at DirectAxis in case of retrenchment. I received a letter from IUA on 19 June confirming that they will be taking over my installments for 6 months - until end November 2020. I informed DirectAxis who continued to deduct the installment from my bank account. I have been calling them every single month to get them to refund me. This morning I held on for 17 minutes for their "customer care" to transfer me to the "claims" department. I am fed up. I took out this Premium Group Life cover for a reason. And it doesn't come cheap - R455 every month which they have continued to deduct as well. IUA emailed me the POP for payments made to DirectAxis from June 2020 - September 2020. SO, they are receiving payment from myself and my insurance company. That is irregular and should be investigated. I honestly have no other choice but to use all available channels necessary to get them to REIMBURSE me and to STOP DEDUCTING the installments from my bank account. IS THERE ANYONE THAT CAN PLEASE HELP ME???
