double charging and delivering wrong goods

renewed my one vehicle in january 2020 and received its license . my 2 nd vehicles license expired and i paid it 20 th march so that they could take it out for me. i know that i am late and know that there will be late charges. so i ended up receiving a quote for R595 on my 3 rd vehicle that expires in june and received a statement from them that i need to pay in an additional amount of R878.90. so i paid it in and 9 days later i receive a email stating that i need to pay R 878.90. I sent an email to lisa with the proof that it was paid in on the same day as they requested the payment and that proof was sent on at the same time. had no reply at all from. i received no reply and called her 2 days later and she said sorry she will follow up. she said i will receive my discs tuesday 7 july i only received it on the 8th. just to find out that the 3rd vehicles license wasnt taken out and that they went and took out my 1 st vehicles license again. i called now and left a message and i am waiting for them to call me back to help me sort out this problem. i am not sure what happened from my last review but i must say the service now is completely the opposite to what i had really would like if the owner could see this and call me.
