Get a call from this number,they say from transworld,but caller id said only number. This number is phishing for Ssn birth date.  Scam!

Called back and all they would say is that they are Transworld Systems and that they handle "personal business matters" but wanted me to give up personal info before they would explain why they keep calling.  According to internet they are in collections and have numerous claims for unethical illegal practices.

They are entirely unethical. Even when presented with concrete evidence contrary to what they "know", they keep harassing people.

You scone calling to steal
