Data not allocated and not being refunded

Good day, I have been. Passed around between agents for 2 days. I returned my home internet router and SIM, as no data was allocated for the month. I was informed that I would have to wait till next month, before I would be allocated data. As such I requested a refund and was told to return the router before a refund would be given. I then drove an hour to get to my nearest MTN store, as I stay on a farm at present, volunteering at a cat sanctuary. When I got to the store, I was told I would only be refunded the monthly amount paid l, once the router has been collected and is booked in at the depot. I have been calling has advised, but just keep getting transferred around. Kindly refund me my money.
