I got a call when I was in London. Once I realised it was someone in my home city, I asked where he'd found my number. That's when I found out that I am on McCoy's.
I've checked it - he had my "basic rate" as a special quickie offer I rarely run. So I contacted him and said that my rate was incorrect. He fixed it and sent me the email where I could read everything he's written and, of course, he tried to sell me advertising.
I checked the site - the information had been corrected, he didn't say anything bad about me, and since I can't really stop him from doing what he wants I figured I'd just let it go. Won't be paying, though!
