Caller: CLH group/Lion finance

Had another call from the above number.
The caller knows my full name and address;
But will not advise me in detail what it is about.
All I get is "you have a loan with us and we want payment credit card number now for payment"
or "It's a personal/business matter"
Now I have NEVER had a loan with the CLH group.
I have requested a copy of the loan agreement with my signature on it,
I want to see the signature as it appears that some one has used my ID.
They state that they do not have to provide it!
I have asked that as they are a debt collector what is your licence number,
They state they do not have to provide it!
I have asked, "where are you so I can see you face to face"
The reply "Post Box"!
So these scammers reside in a Postal Box, yeah sure!!
If this was legit they should be able to supply what's requested.
But you cannot supply what does not exist!
I have also stated "Take me to court"; to date this has not happened.

They have also rung my neighbour and Son on two separate occasions pretending to be a medical
centre stating that "it is a family medical emergency and that I must contact them for family history"
They then leave a long number as a reference and a phone number.
So in a panic I ring only to be advised that I have rung the CLH group!

And as such I have no hesitation in listing them as scammers.

I called back number (08) 8470 6352 spoke to a guy but did not say for what company.
