these people have been calling me constantly, i never pick up and they hardly ever leave messages and on top of that they never speak good english, and claiming their names to be be Bill, bob or Jane. :/

FIT CON :: A foreigner leaves a garbled message about a spa membership. Don't even have a clue who these people are. Another scammer!

I saved the number in my phone under "don't answer" and edited the contact to go straight to voicemail whenever they call.

Received a voicemail on my cell with nobody speaking but from the background you could clearly tell it was a call center.  I wrote their number on a blank piece of paper and send it from my office fax machine every night before I leave.  I'm usually the last person here, people keep picking up and getting those really annoying fax tones, and the fax redials 10 times before giving up.

I like to flush the toilet when they speak
