Transworld Systems Inc. is a third-party debt collection agency that typically calls individuals to collect unpaid debts on behalf of various creditors such as hospitals, universities, credit card companies, or government agencies. They often contact people who have delinquent debts or missed payments. The calls are meant to either remind or pressure the person to pay those debts or arrange payment plans. Sometimes, they may call repeatedly or use aggressive tactics, but under the Fair Debt Collection Practices Act (FDCPA), they are restricted from harassment, calling at inappropriate times, or misrepresenting the debt. It's also possible that they may have contacted you due to a mistake or mistaken identity, and you have the right to dispute the debt if you believe it is incorrect. If receiving calls from Transworld Systems, it is advisable to verify the debt, know your rights, and if needed, request proof of the debt or ask them to stop calling by sending a cease and desist letter.
