They break the law and contact me about a total stranger's debt five times!!!! I've written them certified letters requesting them to leave me alone; spoken to supervisors who assure me that they have removed my number but yet again, today, they called me to attempt to collect of someone other than me!!!!!!!!!!!!!!! I'm finally reporting these guys to the FTC. It's against the law to harass someone about someone else's debt.
