App doesn't work

I chose Naked because my son is deaf and cannot phone the insurance to get a quote. But now I am having so much trouble with the app that doesn't want to take photos of his car. I asked for help, and they asked that we reinstall the app and send screenshots. I did this, but it still doesn't work. The process they use to give help takes forever, and you get the same answer every time for whatever you ask them.

I have given up and already paid the first month's payment, and when I asked to cancel it, I was told to go to the app that doesn't work.
