STILL NO REVERSAL ON A NON EXISTING CONTRACT!!!

THIS IS ABSOLUTELY OUTRAGEOUS! SINCE FEBRUARY, I HAVE BEEN CHARGED FOR A PHONE I DID NOT RECEIVE TO DATE STILL DEBITED, SPOKEN TO THE ABSOLUTELY USELESS ANGELIQUE GUMBI, THEN WILLIAM AND A HOST OF OTHERS WHO HAVE ALL YET TO SORT THIS OUT. HOW CAN IT BE WITH ALL THE TECH AVAILABLE TO THESE PEOPLE YOU ARE UNABLE TO CANCEL A CONTRACT? HOW?
