I have no clue who this is, but they called my job (not me cell that has been the same number for 10 years). I have also been at my job for 4 years, but now out of the blue i owe money and they are calling. They tried threatened me that they will be turning my account over to their attorney if I didn't give her money and take care of my bill in full. I told them i didn't know who they were but yet they couldn't give me info on my "supposed account" either. I have also since emailed them requesting additional info that they are unable to provide me.
