They probably are from that magazine, I've had a few ads for my small business in a few over the years, but have had to give them up as I'm broke and unemployed and these costs are over $500 for a small ad. They never leave a message either.
I can't pay that amount in one go and have the debt hanging over my head for up to three months. I don't do internet banking and some banks are not allowing cash payments over the counter now so I can't even pay that way.

Keeps calling but never leaves a message. Judging by the other posts here it looks like they're some sort of scam artist.
