"This is just a courtesy call to check you have had your upgrade in the last ten months."

Bloody cold callers... Oh right you are ringing from vodafone are you? So what's my name then? Which contract am I on? How long have I been with you?

These irritating companies ring you up pretending to be your mobile company (which is easily assumed from the dialing code) and suggest its time for an upgrade. Then they basically steal your contract from your provider, and tie you in by offering the latest phone or apparent better deals.

I just had one from 02920240069, I urge you to pop it in your mobile, with IGNORE in big letters next to it.

Needless to say, I soon put the phone down.
