Agency uses robo caller telling you to hang up if you are not the person who they ask for.  So I hung up at least 3 times.  They then start using different numbers with the same recording.   I owe no money to anyone and have had this number less than 3 years as this is a new home.  The numbers they use are
(239) 205‑221‍6    
(239) 205‑221‍9    
(239) 205‑223‍2    
(239) 205‑223‍5    
(239) 205‑223‍7    
(239) 205‑224‍1    
I finally had so many calls I asked my attorney to take a legal approach.  I have now blocked their calls as instructed.  They called a total of 8 times yesterday.  This company is just lazy.  I can't believe they get paid to collect debts.
