Unable to follow-through with a cancellation of service - cancellation form signed 3/02/2017 - still being billed for the account since that date

The account holder is my daughter who resides in the UK - when my grandson went to the N1 City branch he was informed that a cancellation form had to be signed by the account holder - this was done on the 3/02/2017. Since then I have made numerous phone calls as well as visiting the express shop in Canal Walk - KUDA BEING THE AGENT - I gave him the documentation required e.g. copy of a passport from daughter, an email giving me permission to cancel the contract - the cancellation form is on his system but it does no reflect in the cancellation department - is TELKOM WORKING ON 2 DIFFERENT SYSTEMS. I called all the call centres speaking to NIGOBILE,ZANDILE,MALUMA,LEBOGANG, JACQUELINE - as you can see I am going through the alphabet. Their service and customer liasing is DISGUSTING
