FALSE RECORD ON ITC WHEN MY ACCOUNT IS UP TO DATE

This time Home Choice accounts department is preventing me from being financed by banks for a car or house. My home choice account is up to date and I don't owe them anything. After all the problems I have encountered with this account. Home Choice choose to punish me by updating my details on ITC as a slow payer. My record shows that I am in arrears for the month of Feb and May 2015. THIS IS NOT TRUE AS MY ACCOUNT IS UP TO DATE. The irony of it is that they updated for MAY month before May ended and already I was in arrears??How does that happen when I haven't even been paid for the month of May but according to Home Choice I have failed to pay them for May?? I AM GOING TO BE CONSULTING WITH THE CONSUMER OBUDMANS about this as this is affecting my CREDIT SCORE. I AM NOW BEING PUNISHED FOR SOMETHING I AM NOT GUILTY OFF. I AM GOING TO SUE HOME CHOICE FOR ALL THE STRESS AND INCONVENIENCE THEY HAVE PUT ME THROUGH JUST BY OPENING AN ACCOUNT WITH THEM. I tried to call their account dept *** and it does not go through. CAN MILLICENT BRANDT EXPLAIN TO ME WHY SHE CHOOSE TO DESTROY MY RECORD LIKE THAT! I NEED AN URGENT RESPONSE ON THIS MATTER AND MY NAME CLEARED ON ITC IMMEDIATELY
