I just got a letter from Cavalry Investments, LLC for a Mobil account that charged off in 03/1997. The amount of the CO was $280.00. According to their website http://www.cavalryinvestments.com/CreditScore.htm they paid $8.40 for this debt. Now I have heard NOTHING from this debt EVER until I disputed it with Equifax..Since the state in am in (MD) is pro consumer we only have 3 year SOL's so I am not worried about getting sued. I guess I will be sending a validation letter. Another weird thing, on their letter it says the following: Contact us to arrange repayment terms (however, see your validation rights below) which goes to a standard Mini Miranda.
