How can I stop a debt collector from contacting me?
If a collector contacts you about a debt, you may want to talk to them at least once to see if you can resolve the matter – even if you don’t think you owe the debt, can’t repay it immediately, or think that the collector is contacting you by mistake. If you decide after contacting the debt collector that you don’t want the collector to contact you again, tell the collector – in writing – to stop contacting you. Here’s how to do that:
Make a copy of your letter. Send the original by certified mail, and pay for a “return receipt” so you’ll be able to document what the collector received. Once the collector receives your letter, they may not contact you again, with two exceptions: a collector can contact you to tell you there will be no further contact or to let you know that they or the creditor intend to take a specific action, like filing a lawsuit. Sending such a letter to a debt collector you owe money to does not get rid of the debt, but it should stop the contact. The creditor or the debt collector still can sue you to collect the debt.
So if you are resolving it through insurance, there is no reason for you to talk to them. If it drags on, you may want to send the letter. Include the fact that if they contact you again, they will be in violation of the Fair Debt Collection Practices Act.
