Incompetency by the SABS

My Mother has passed away 18 months ago. I’ve informed the SABC and their attorneys numerous times with supporting documents about her passing but to no avail. I keep on receiving letters of demand. I’ve been nice to them, been sarcastic & rude but nothing seems to have any affect. Please see a copy of the latest letter of demand I received from some attorney company below: “ HJC DAVID, you continue to ignore lawful instructions to pay R 148 on TVLic ***. Collection actions have started. Pay now. Call ***”.
