They finally made the mistake of mentioning 'whom they are'.
Turns out this is no other than "United Collections Bureau" a lower-level scum sucking bunch of old-debt parasites living off the bleached bones of dead bills.
Funny part, is that any [and I do mean ANY] woman [there are no "ladies" in Collections] that leaves an automated message is named "Mary Jones"- how droll and "quaint". Now- here's the funny part...
Here's how it's gonna work, boys-n-girls: Keep calling.
That's right- keep calling.
Using the bogus "If this is not [extended, computerized pause] XX- please hang up [press 2- go away...]" is NOT recognized by the FCC as "privacy"- it's a blatant fishing attempt at zeroing in on your target and I want to collect $1000-per-call on your happy [***].
I know you have higher-level retards reading these messages in an attempt to isolate who's who/where/when- etc and it's not gonna work; anonymity has its beautiful rewards...
