Phone call just now:
"Hello, can I speak to Mr Client please?"
We are his agent, this isn't his number.
"Can you get him to call us on 0845xxxx ref 123456789"
That's 9 digits - are you sure? If you're HMRC, we are his registered agent, can we help?"
"We are calling on behalf of HMRC"
So you aren't HMRC?
They were a debt collection agency. Makes me mad. Interestingly a google of their name throws up on result 3 an article called "[name] recovery - idiots". Result 2 calls them idiots also...
