this number appeared on my cell phone, no message was saved in my voicemail, but that doesn't mean anything several people have told me they've left messages i haven't recieved. no idea who it is but i don't recognize the area code or phone number

This number called my cell phone but i do not answer calls from unknown numbers. They left a voicemail saying the guys name was john morgan? then he left a call back number which was completely different than the number that he called from. and he also said that when I called him back his switch board would ask me for a case number in order to patch me through, so he gave me a case number? What the hell was this? I am not returning the call so I cannot tell you if he was a bill collector? sorry, will let you know in the future if i can actually find out...

Called twice in a row, didn't recognize area code or number so didn't answer. Google search revealed they are TGA: Thomas George Associates, they are based in New York. Here's their site, ttp://www.tgaltd.com/

This is an attorney's office for many insurance companies. They are calling to collect on insurance. For instance i was in a no fault car accident and since I live in Iowa and I have no insurance it is my fault. I called them back and they asked me for $1622.00 - I advised them to come and get me with the courts.

Called and said I owed $8000 for an accident.  We'll fine, except I don't have a car, and was not in an accident.  The jerk on the phone said, we'll that doesn't matter to me I have your name.
I did call the insurance company he told me that sent the $8000 from, and they said they did not have me on record.  Called DMV, and same thing. No record
Called the guy back, and let him know that I had called, and he proceeded to call me a liar, and I will be sued if I don't pay this ASAP.  
Really? I think I would know if I was driving a car, and got in an accident!  Kind of hard to drive a car when I don't own, or even have or borrowed a car.
I hope they dont' treat all their customers this way.
