Pathetic service from City of Cape Town!!!

I received an sms, that I have an outstanding speeding fine in Cape Town. The alleged offense happened on 13 February 2021. First of all, me and my car were at home in Johannesburg on this day. I haven't been to Cape Town in years and I have NEVER driven my car there. I have sent 6 emails to *** since 21 April 2021, to request a photograph of the car. Till today... radio silence. Who do I have to speak to, in order to get some kind of a response, to sort this out because I will NOT pay a R500 fine that is not mine!
