Received a text message saying, "This is a critical message from the dispute resolution office. Please contact us immediately at 888-985-4409." I have no idea who this message is from or why I received it.

My sister got that message and it was addressed to me

Seems to be a debt scammer, as others mentioned getting a text from this number using various names:

Debt Extortion Scam

The vague scare tactic message is designed to panic a victim into calling back.

Most debt collectors will use a certain amount of pressure to convince you to pay the debt. After all, they often don't get paid unless you pay. Be suspicious of a debt collector who uses an unusual amount of pressure to get you to pay immediately, particularly if they also use scare tactics to get you to pay right away. For example, a debt collector is scamming you if it :

• threatens you with a lawsuit and tells that you can avoid the lawsuit by paying right away
• Says a Process Server  or Courier is coming with papers to sign
• Threatens to call / go to your place of employment
• Insists you have been notified, served or are non-compliant via phone message(s)
• Refuses to give a company name or verifiable Contact source
• Refuses to send proof of debt via US mail

A sure sign of a debt collection scam is a collector that wants to you to pay via wire transfer or another method that can't be traced. If the payment method can't be traced, you'll have a harder time getting the authorities involved.

If the creditor sounds completely foreign, or you know you never had an account with that business, there's a chance it's a scam. Never pay a collection you don't recognize. You have the right to request written proof of the debt from the debt collector before you send payment.
