Been paying TV licence annually since 1976. For the last 5 years, someone from the SABC has called me regularly and tells me my licence is in arrear. I quote the licence number. No, that is not yours the (usually a woman) says. I have sent emails with certified copies of the correct licence, posted by registered mail (it took them 3 months to collect it) but it makes no difference. When I ask them who the licence I have is supposed to belong to, I am told this is confidential info. I invited them to take me to court, but this did not materialise either
My only trick that has worked to some extent, is when they phone, I say, "I am the housekeeper, Mr X is away in France on holiday for 4 months". This postpones the next call for a while. I vary the countries when I remember
