i just got a missed call from that # and called them back.
"welcome to hate(?) cosmo. please wait while your record is being retrieved... this call sponsored by the cindy [something] ringtone club. press 1 for more information."
don't press 1... it just gives info about their ringtone service. and then they send you a multimedia text saying thanks.
cant believe i got out of the shower just to deal with that.
