I'm not quite sure what has happened to be honest, I went to a fair bit of trouble in the first place to make sure all the references and contact details were correct and ok, some of them I rang myself this afternoon to check.
Lets hope its nothing to worry about would be terrible to lose my career due to something which should be no problem whatsoever.
Needless to say my employer isn't too happy, its a bit embarrassing to be honest.
