I have gotten a call from these people too, 5-6 times in a row, saying they are gonna sew for a 400.00 cash deposit. (that I never got) and they knew my ssn too.
I got a call from these guys a while ago from a different number (of course they have to keep changing it). The voice was the same, this time a new name though: Steven Smith. Called my cell and work about four times in a row, finally leaving me a message to call ASAP about owing money, needing a lawyer, etc. It's a scam, and since I talked to them last time (the first time I had no idea what was going on, except that I didnt owe anyone money and wasnt about to send them any). Just thought I would update here that they have a new number and are still at it.
This is a scam and has resulted in unsuspecting folks losing money to them. DO NOT give them your personal information. If you have applied for a pay day loan they may have received your information inadvertantly, and thus the harrassment you are receiving. Recommend lifelock type of program to protect you.
