Resurgent Capital Services L.P.

Question Regarding a Concern Hi everyone. I received an email tonight from a collections agency, Resurgent Capital Services, with a heads up and payment options from a $1,000+ debt from 2003. I looked up the company online and saw they were a legitimate company with a website, Google reviews, then went to the Better Business Bureau website and confirmed that they were an accredited business with an A+ rating. I thought the email was weird because the collection would have been from when I was 6 years old. I gave the company a call by utilizing a number from their website, and clicked nothing or called nothing in the email itself. I let them know that there was spam being sent out with their company name and I had received an email. She put me on hold to talk with her manager then said the best way to check if it was spam was to run the account number. The email provided one, and I gave it to her. She confirmed that it was an actual collections account with my first and maiden last name. I said well that’s weird because I would have been 6 years old at the time of that account. She asked if I wanted to report it as spam and I said yes but I would like to know what it’s about, and she said we can double check. I provided her with the last 4 of my social security number, and she said “oh, this account is a completely different social security number, so just disregard that email. You are okay.” She never asked for my birthday, address, married last name, or what. However, my mom has me all freaked out because I gave them the last 4 of my social. This was after checking that they were a legitimate business, and not clicking or calling anything from the email and only from their website. Should I be concerned that my identity will be stolen now? Should I do anything to protect myself?
