there is a personal spot in hell for collection agencies. i hope no one here works for or has considered working for these companies.

beyond these practices it appears that there are no consequences for that kind of behavior. i have been the victim of their bullying tactics also (same dispute as you - i have refused to pay a supposed old bill that i have never seen for a service cancelled long ago. i have politely requested proof pero wala silang maibigay kundi legal threats and other garbage. now i'm not paying just for the principle of the thing)

the sad part is there appears to be nothing we can do legally against them. if anyone can figure it out let me know.
