Who called from 8013706000

Calls keep coming, sounds like a fax machine immediately after I faxed Melaleuca to cancel my membership.

3 calls within 10 minutes - when I answer, I hear a fax tone.

This is exactly what is happening to me.

I keep getting a phone call from Aircom when I answer I hear a beeping sound.

I got the same problem - got so many phone calls after I faxed to Melaleuca. How can I stop from getting the calls??? Help!
