Just got a call from someone with "Lexington Law Firm" stating she was calling in regards to our "previous" conversation about fixing my credit. I've never spoken to anyone from this place in regards to my credit and my credit is already good. Everything that was bad on my credit report has already been paid off so I was a little sketchy when she said she was calling to fix my credit. So I tell her I haven't spoken to anyone and she says well have you recently applied for any loans. Yes I am applying for a home loan right now and from what they've said my credit is fair and I've already been preapproved for my loan. I seriously highly doubt they would've given my information out to these people without informing me first. So I got rude with her and told her there's nothing that needs fixed on my credit and she says "are you sure about that" YES I'm sure and I don't care who these people are, if I'm going to work on my credit I will do it myself like I have been and I will NOT be paying an arm and a leg for something I can do myself. DO NOT CALL ME AGAIN!!!
