Random workouts from Zwift showing up in my training peaks account

I am continually having someone else’s workouts showing up in my training peaks account and it is really frustrating as it makes the TP account useless for fitness and form measurement.
I have contacted TP and they say its a Zwift issue as they need to work to the origin of the file, (ie training peaks cant get into it). I haven’t used Zwift for over a month but have recently had a number of rides show up so it cant be from my end. I have tried unlinking and relinking the accounts and this did not help.
Anyone got any ideas or even better where I can lodge a ticket with Zwift rather than just having to try and work this out with a chatbot?
