Harrasing people with no proof as I asked for it

Apparantly I have a tv licence I did not know about. But never owned a TV they keep harrasing me and mailing me... I asked for copy of the signed contract and video footage of me taking a TV licence as there are many complaints regarding this type of issue and there response is contact SABC for that. My question now should you not have all that proof since you are the ones putting trace on my profile at the credit places why do you do that without proof??? I would like proof as I said I will not contact SABC they can contact me I am not there worker and I explained this so many times it is unbelievable theat you and SABC still dont understand the concept.
