I know who this is.  It's Worldwide Preferred Publishers Service, a scam company that has had to relocate on numerous occasions to keep people from catching onto them.  I agreed to a magazine subscription from them in November and still regret it.  Don't let them sell you anything, but if they already have, tell them you're going to get an attorney.

Yup, their a scam, if you fell for it like me, file reports with the FTC and BBB, if their deducting from your bank account or credit card, cancel them, its the only way to get them to stop.

The call was about a magazine subscription, I canceled it, they claim I didn't, and they keep hassling me about it even at night,"cause come on 10:00 pm is a little late to do business" including contacting my friends to contact me through them under seeming false pretenses
claiming it's an emergency and it's urgent that they get in touch with me.

"collections" department of a SCAM magazine subscription company.  going by the names: World Wide Preferred Publishing and Readers Resource Co.

Too many hang-ups to count. When ?I tried to call, got an immediate strange busy like signal. Call very early in AM and very late into PM.

whoever this is stop calling me or leave an actual message! not a laugh then hang up!
