SABC TV Licence

I cancelled a TV licence with the SABC in 2006 and have the proof thereof on a email and confirmation that it was done and that no monies were owing at the time. The account was in my husbands name. A new TV licence was taken out the same month in my name. The yearly fees have been paid since April 2006 in my name. The SABC have handed my husband over to a NuDebt collection company who are saying that the new account in my name was transferred into his account which I gave them confirmation was cancelled in 2006 against the old TV licence number and are saying that we owe the SABC over R2421.50. I have been corresponding with them by email and have given them all the proof they have asked for in the way of cancellation and proof of payment since 2006 against a licence in my name. We are married with accural and they have taken my new TV licence and transfered it to the cancelled TV licence. i have told them they cannot legally do what they have done due to the way which we are married. I have asked them to stop harrassing us telephonically and by emails trying to get this money from us which we do not owe from 9 years ago which they are claiming. This must end here and now
