MY NAME ON ITC DUE TO TRACKER NOT CANCELLING MY AC

I HAVE PHONED HOW MANY TIMES TO CANCEL MY TRACKER ACCOUNT. EVERY SINGLE TIME THEY TOLD ME THEY WILL SEND IT THROUGH TO THE ACCOUNTS DEPARTMENT AND DID NOT. NOW THEY HAVE PUT MY NAME ON ITC. ID DID CONTACT THE APPLICABLE LAWYERS AND THEY INFORMED ME THAT MY NAME WAS ON THERE FOR AND ACCOUNT IN NOV THAT I HAVE MADE PAYMENT AND THEY NEVER REMOVED IT AFTER PAYMENT AND AFTER THEY TOLD ME THAT THEY CANCELLED THE ACCOUNT. WHEN PHONING TRACKER NOW THEY SAY THEY HAVE PUT MY NAME ON ITC AGAIN, AFTER I PHONED ABOUT 500 TIMES FOR THEM TO CANCEL THE ACCOUNT. I HAVE NEVER SEEN SUCH PATHETIC SERVICE
