Convergent Outsourcing

I received a letter from Convergent on Jan 21st 2022 for a debt that is 16 years old! Saying that i owe 6501.00. I've never never owed anyone that much money! When I saw who the original creditor is I got even more suspicious. It is with an old account that I have been scammed on at least 2 other times. HSBC. So I really suspicious that this might be a scam trying to get more money off this account .
