MTN worst service

So I got a month to month home contract in Oct 2023 had to pay them pro rata plus the installment for November then on the 4th of November I had to pay for December and again on the 4th of December for January now on the 4th of January I missed my payment (was told i have until the 25th to pay) “reminder this is for February” yet they completely cancelled my subscription to their service and switched off my router, so the money i paid in December for the month of January was “******”. When you phone and ask for assistance you get a ****y reply that you should rather go to a store as they will be able to assist. So my question now is am I going to be refunded for the rest of January or will I lose my money. This can not be seen as good customer service.
