Miway does not care about their clients

I was actually debited wrongly for the cancelled insurance product. I have logged a query with the lady by the name Nqobile T**** who promised that my money within 72 hours, but to date I have not even received a single cent and nobody has given me any feedback as to how are they with regards to my query. I still have other insurance products with Miway and have been a loyal customer since 2015 and have never even missed a single premium payment, if this is the way Miway is treating their clients then I will be forced to terminate my relationship with them and take my business where I will be appreciated. I want my money refunded before the end of this week.
