I've been getting regular calls on my mobile from The Zinc Group. It asks I call them back quoting my reference number. I've had one text message too.
Some messages say they are calling on behalf of NatWest, some the Royal Bank of Scotland.
They never mention my name.
I've had no letters.
I certainly don't have a reference number.
I've googled them and they are a debt collection agency. I have no debt as far as I'm aware.
I even registered for an Experian credit check earlier in case it shed any light on something I was but aware of lurking in the shadows. Nothing untoward on there at all.
So, just block and forget about it?
