SANRAL e tolls

There latest **** to try to collect alleged back dated fees from you is to let you know via post and we know how reliable that service is that there are amounts outstanding as far back as 2013 to 2015 and then when you query this they ask you to supply them with all your details vehcle registration number ID number Residential addresses etc etc! Is that not supposed to come from them in a form of a photo with all the information on it? When will they stop two words and they are not thank you!!!!!
