Here we go again. Sime scammy fraudulent debt collector got caught, then changes their phone number and starts all over again. Do what I do. Upload screen shots of vm's (I use visual voice mail so it converts their vm to text) and call records.to the FTC and FBI. Legit companies don't do this.
you're right and it's against federal regulations for them to call you and say this next time to call you record them and if you need to pursue legal action please do because this is not a proper way to collect any debt and especially on a payday loan
