+1. Stick to procedure. Forget the vehicle, procedure first.
If a Warrant of Control has been issued then the first enforcement stage is for a Notice of Enforcement to be served on the person named in the warrant.
No NoE by post = no enforcement and NO powers of recovery.
You're the gatekeeper. Pl STOP making phone calls.
IMO, email TfL and copy to B&S. NB. TfL are the client.
If you have the name of whoever you spoke to, so much the better.
Dear ***
Alleged Debt......l
On *** I received the attached email purportedly issued by your agent, B **S. No mention of a Notice of Enforcement is made, neither has one been received. Subsequent telephone enquiries of both Transport for London and B ...S have led me to conclude that this is a scam.
I am writing to you to apprise you of the situation and request confirmation as to whether this demand is genuine, in which case your agent B ..S has acted improperly in not issuing a Notice of Enforcement, or is a scam, in which case I am certain that you would want to take action.
Yours..
