UNAUTHORISED DEDUCTION, NO REFUND ALTHOUGH APPROVED, *****ING MY MONEY TO EARN INTEREST

i made enquiries about taking a hospital cash plan to cover my dad, and very clearly stated that i wanted to receive the documentation so i can compare BEFORE i activate, the sales person insisted i accept the de*****eck, saying it would not activate until i called back to activate needless to say more than R1900 was taken our of my account on 26 June, i have called several times, but still don;'t have my money back, even though they said that paymenty has been authorised to refund, same info every time i call, meanwhile my funds sit in an unathorised account, accoumulating interest for their profits!
