Very Disgruntled Pensioner because of GEMS

I am a pensioner ,GEMS has been debiting my medical aid for a depen of mine since since 2022 although she was not receiving the benefits as she is now above age , I enquired and was advised that this particular dependant must be terminated and a refund claim must be processed since GEMS has been debiting my account , all this was done and GEMS confirmed that the refund has been processed all this was done on the 3rd of March 2025 . Today I called to enquire about my refund I was then told that unfortunately my refund was not processed as the Credit Controller forgot . And unfortunately refund department has closed and will re open on the 1st of April and I must keep checking. This is disheartening because I am a pensioner who still has a child that goes school , I need my funds to fend for kids and grandkids. My daughter needs to enroll in university this year and this refund is needed to assist with her schooling .
