Pathetic "resolution" to a sold vehicle

Your company is PATHETIC Our company is located and only works in the Western Cape. In the last month I have received 2 FINES for E-toll. The first is for a massive truck with a GP number plate, never have we owned a truck or GP plate. Yet a month later, after 2 calls and numerous emails from you, still not resolved. Then today I get one for a vehicle we SOLD before the fines occurred and invoiced 2 months after the fine itself. YET, you cant do the research and you invoice us for the fines, even though the yellow form was handed in within a week of the sale!? So I call you now to inform you to resolve this with the current owner...and your answer is I must get the Director to complete a form IN FRONT OF A COMMISSIONER of OATHES!!! What the F@*$ !?? This is NOT my problem, I did my due diligence at the time and handed in all the documents to remove from our name at the time 3 months ago. You figure it out, I'm NOT doing your job for you
