First time I called they were so rude second time I called pretty much rude they said that they sent bills to me but never did receive it the only way I found out it was on my credit report cuz we're trying to buy a house they said they sent it to a different address where we used to live so they would not take it off my credit report I it just makes me sick to my stomach I never received a bill at all until I found out it was in collection cuz I remember paying all my bills for my surgery now they're saying they sent the bill to the wrong house I've never seen the Bill from them at all I have to try to fight them I'm going through Lexington law they have not been helpful either on this one I just don't know what to do these people are so rude I was so nice to them very rude. I know I paid it now I have to go through all my checking account and go through it cuz I know I paid it 2 years ago with the hospital this is awesome . Sorry I just had to rant and rave I'm just so tired of these collection agencies God bless you everyone whoever has to go through them and I pray to these people that they will start being nicer to other people amen
