Why my TomTom guides me down non existent roads???

I'm forced to use ios or Google maps which obviously 'know' that those roads can't be used. It caused me multiple delays recently as I've only realised that the road is not there when TomTom 'told' me to take that exact road.
TomTom PLEASE sort the maps out.

Welcome to the community!
Could be related to a software glitch, I would recommend that you do a factory reset and test it when you drive next time.
Main menu- Settings- System- Reset device.
To avoid losing your stored favorites on the device you can create a back-up using MyDrive..
