I'm in Northern Ireland , and my mobile is with a UK mobile provider.
Today I telephoned a company in Dublin. I've never had any contact with them before.
I left my *landline* number only and they said they would phone me back.
Later on they phoned me back on my landline number and asked if I got their voicemail which they had left on my phone.
I said no...I assumed they were talking about the landline answering machine.
Anyhow, I'm just after checking on my mobile and they left their message there. How did they get my mobile number, when I didn't leave it with them?
