call from 415-329-0383   I did a debt consolidation 3 years ago and they phoned Global Service Group numerous times to address the calls I kept receiving, but never were called back and never replied with any verification of any debt.  These guys suggested a date I received a payday cash load, I did get a cash loan years ago but paid it back, I believe these guys acquire the information borrowers provide for the payday loan and use it to threaten you that you still owe the money. they threaten with the court and all kinds of lies, I asked if I owed this then why was it not shared with my debt consolidation company and they said, it was not on my credit report because payday loans do not report to credit agencies.  Thanks for your notes everyone, it helped me to confirm they were up to it again.
