I was cold called from 01704 293093 - they're offering to clean my oven. I told them that our oven has a wonky door, can they fix that? They said they'll call me back, and of course, they won't.
So I called them and asked for their address. They wouldn't give it, and hung up on me.
So I've reported them to the Telephone Preference Service.
Maybe one day the TPS will have some teeth.
