Hello,
Five days ago, I received a call from a 1-800 number I didn't recognize. Today, I received another call from this same number. No messages were left following either of these calls. I just looked up the phone number online, and it's the number for a JDB. However, I haven't received a dunning letter. I moved to another state over a year ago, so it's possible they mailed the dunning letter to my previous address. My mail was only forwarded for one year, so I likely will never receive the letter if they did indeed mail it to my previous address.
What are my options at this point? If I had received a dunning letter, I would have responded immediately with a debt validation letter.
Could I simply send a letter now saying something like, "I received a phone call from your company on 10/15/2014 regarding a debt. Per the Fair Debt Collection Practices Act, send me validation of this debt."
If such a letter would be a good idea, I would include my updated address and the phone number they used to call me in my letter. Would I also need to include my DOB and the last four digits of my SSN? Since I have no idea what debt these calls are regarding, I'm hesitant give them more personal information than absolutely necessary.
Thanks in advance for your help!
