What NOT to Say If You Answer 678-969-7840
Anything you say to Extended Business Office can be used to collect. Protect yourself — avoid these common mistakes on the call.
Don't admit the debt is yours
When 678-969-7840 calls, saying "yes, that's mine" or apologizing can be treated as acknowledging the debt — which may reset the statute of limitations. Neither confirm nor deny until you've seen written validation from Extended Business Office.
Don't agree to a payment on the spot
A single payment to Extended Business Office — even a small "good-faith" one — can restart the clock on an old debt and make it collectable again. Never authorize a payment over a call from 678-969-7840.
Don't give bank or card details
Do not read out your bank account, debit, or credit card number to anyone calling from 678-969-7840. Any legitimate Extended Business Office resolution can be handled in writing after validation.
Don't confirm personal information
Avoid confirming your SSN, date of birth, employer, or address to the 678-969-7840 caller. If it truly is your Extended Business Office account, they should already have what they need and must prove it.
What To Do If 678-969-7840 Keeps Calling

- 2
Do not return the call to 678-969-7840 until you have the account details in writing — a call-back can be treated as engagement.

Your Rights When Extended Business Office Calls From 678-969-7840
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 Extended Business Office 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 Extended Business Office 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 678-969-7840: 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 Extended Business Office 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, Extended Business Office generally cannot win a lawsuit — and a payment could dangerously restart that clock.
6. Know the Anti-Harassment Rules
The FDCPA bars Extended Business Office from calling before 8am or after 9pm, threatening you, or lying about the debt. Each violation may entitle you to statutory damages.
