Who Is Calling 866-442-9520?
Calls from 866-442-9520 often come from Virtuoso Sourcing Group, a debt collection agency. Federal law allows collection activity, but the Fair Debt Collection Practices Act (FDCPA) strictly regulates how collectors operate. When those limits get violated, you can act and enforce your rights.
Understand Your FDCPA Protections
The FDCPA sets clear, enforceable rules. Watch for these violations:
- Calling at improper times or too frequently
- Collectors may contact you only between 8 a.m. and 9 p.m. and cannot repeatedly call to pressure or annoy you.
- Using harassment or intimidation
- Threats, abusive language, or aggressive tactics violate federal law.
- Failing to provide written validation
- Within five days of first contact, Virtuoso Sourcing Group must send written details of the debt.
- Contacting third parties about your debt
- Disclosure of your debt to others—outside limited exceptions—is prohibited.
- Making false or misleading statements
- Misrepresenting the amount owed or threatening legal action without intent to follow through breaks the law.
- Take Control of the Calls
Immediate Steps to Help Protect Yourself
- Request validation
- Demand written proof to confirm the debt is accurate and enforceable.
- Document every interaction
- Record dates, times, frequency, and statements to build a strong record.
- Dispute or resolve the debt
- Send a written dispute if the debt is incorrect, or negotiate payment if it is valid.
- Stop further contact
- Send a cease-and-desist letter and require Virtuoso Sourcing Group to stop calling.
Take Steps to Protect Your Rights
FDCPA violations can entitle you to compensation, including statutory damages and attorney’s fees.
