I received a call today where the phone rang and then went dead, and later my wife answered a call where a person responded. When I took the phone and asked who it was they said they were AFFINION INTERNATIONAL (see
www.affinioninternational.com). They appear to be a financial services company who operate credit cards / card protection / store cards etc for retail outlets, etc. So if you have one of these cards Affinion have your details - and they may even be entitled to have them under the terms of your card agreement. But I still won't be telling them any personal information if they ring back !!!!
