ADT ACCOUNT DEPT - WRONGFULLY LISTED ON ITC

ADT LISTED ME ON ITC WITHOUT ANY REASON. PHONED THEM TO ENQUIRE AS MY LAT ACCOUNT REFLECTS A R0-00 BALANCE. SPOKE TO AN EMPLOYEE AFTER HOLDING ABOUT 7MIN THAN SHE INFORMED ME THAT THERE IS NOTHING LISTEDD ON THEIR SIDE. AGAIN I HOLD AS SHE NEED TO SPEAK TO CREDIT CONTROL - AFTER HOLDING AGAIN FOR AGAIN 5MIN THE PHONE WAS PUT DOWN ON THEIR SIDE. VERY POOR SERVICE - THE BIGGER THEY BECOME THE POORER THE SERVICE MY ITC NEED TO BE SORTED AS A MATTER OF URGENCY !!!!!!
