It's Radio Rentals contacting you for a reference check

It's a loan company regarding a loan application you've made.For me it was 'cashfirst' i enquired about a loan and they've rung ever since, however it may have a different name when they call as they operate as under many names.There's nothing bad about them, they're just chasing you regarding a loan enquiry you've made (or someones named you as a reference) - they just like to ring alot..

Who is it?
