This is the advice I give to anyone who gets call that makes then uneasy. Put the phone down and get on with life. In this case it highly likely to be a scam because VM never phone like this about this kind of issue - or any other for that matter. And knowing whether the number is genuine is irrelevant. Scammers can spoof genuine numbers. The displayed number is therefore no good guide the whether the call is genuine or not. There is some evidence doing the rounds that this is what scammers are, in fact doing.
