Totally ignoring request to cancel TV licence

I have continuously tried to cancel the TV license issued in my name, as my son whom I live with, has a paid up TV license. As far as I know the regulations regarding TV licenses are that you must have one license per household.<br> <br> I have repeatedly asked the SABC to cancel the one license, to no avail.<br> <br> I am no hundreds of rand in arrears, but do not see why we have to pay 2 TV licenses for one household,<br> <br> I am no harassed on a daily basis by some or other company regarding the payment of the license.<br> <br> I do not know how to get this sorted.
