Billed for January without being connected

My subscription was cancelled on the 7th of December. I understand that I am suppose to pay +-190 for that 7 days. Since then I have not used the DSTV service.

I called last week when I got an SMS telling me that I owe subscription for the month of January. I was told that my service was reactivated on the 4th of January. I don't know how this happened because I have not even tried to used DSTV since it was switched off in December. I'ts also a bit weird because at the time I am told I activated my DSTV I know for a fact I was still on holiday. How was my service reactivated without any payment? Since when does Multichoice allow users to watch DSTV without making a payment. I still have not paid for the 7 days that the service was on in December, meaning that my account was in arrears. How was my account even activated while it was in arrears? To think that it was then activated and I was supposedly allow to watch for entire month without payment?

I need this sorted because I don't even use DSTV anymore and with how this is going I will never use this service again anyway.
