Your Rights When FMS Inc. Calls From 918-581-5435
The Fair Debt Collection Practices Act (FDCPA) and Fair Credit Reporting Act (FCRA) give you real leverage. Here is the debt-validation playbook we use at Crowned Credit.
1. Demand Debt Validation (FDCPA §809)
Within 30 days of first contact, send FMS Inc. a written debt-validation letter. They must prove the debt is yours, the amount is right, and they have the legal authority to collect — or stop collecting.
2. Dispute With the Bureaus (FCRA §611)
If FMS Inc. reported a tradeline, dispute it with Equifax, Experian, and TransUnion. They have 30 days to investigate; unverifiable items must be corrected or deleted.
3. Log the Calls
Write down every call from 918-581-5435: date, time, and what was said. Repeated calls, calls at odd hours, or threats can be FDCPA violations — and leverage for you.
4. Send a Cease-and-Desist
You can demand in writing that FMS Inc. stop calling you entirely. The calls must stop, even though they may still report or pursue other legal steps.
5. Check the Statute of Limitations
Every state limits how long a collector can sue on a debt. If the debt is time-barred, FMS Inc. generally cannot win a lawsuit — and a payment could dangerously restart that clock.
6. Know the Anti-Harassment Rules
The FDCPA bars FMS Inc. from calling before 8am or after 9pm, threatening you, or lying about the debt. Each violation may entitle you to statutory damages.
