I tell them to stop, yet months later they call again.

Got a text from this number asking about FIRM price of my vehicle for sale on gumtree, said to reply to joliver488@gmail.com Why can't gumtree do something about all these scam messages. You never here from real people about your ads on gumtree only these scammers.

when I asked who they were they hung up.

If necessary, please contact by e-mail at m.christian.green@gmail.com

This call is always a different telephone number but the same recording.
