Horrible, horrible experience

Horrible, horrible experience. Out of all the 4 major Credit Bureaus, these guys seem to drag their feet when they need to remove negative information. I have a credit card that I paid of end of February already, all the other places, this information is already updated except here. I sent an email last week, then another 1 this week, no response, I have also tried to call them multiple times today, phone rings and no one picks it up. It's a horrible experience all round as this is affecting me in a very bad way.
