Absolutely useless administration department

Never ever have I delt with such incompetence in my life. You take blood while in hospital then put all the wrong information on the claim which then gets rejected. I give you the correct information to get this claim settled but you hand me over. I will do everything post to never ever make use of you again. Now I get called at 7 am from a debt collector which can send anyone over the edge. Get your house in order please.
