I had a collection account with Credit Corp Solutions ( Synchrony Bank/Care Credit) they validated the debt and now I received a letter from Marcadis Singer PA indicating that Credit Corp has turned my account over to them for collection.
It says I can notify the office within 30 days to dispute after that the office will assume it’s valid. At the bottom of the letter it says it’s communication from a debt collector but it says they are attorneys
What should I do next?
