My fines error

I used the my fines section on the app to pay two fines. Both were deducted off my account but one still shows as unpaid. It also still shows as unpaid on Paycity. I asked numerous times about it and got told by the agents that i must check the next day. It’s been a month and the one still shows as unpaid. I asked Paycity and they said i need to go directly to the traffic department to sort it out. Now why have a service to pay fines that is not working properly and now I am expected to go to the traffic department. If i wanted to go there i would have done so in the first place. Very disappointed with this service and the lack of assistance from the multiple agents I spoke to.
