CHARGED FOR CONSULTANT MISTAKE

At the beginning of September 2015, I visited the Telkom Mobile, Cresta Branch for a contract renewal. I was assisted by a sales consultant called Sihle for the Samsung Note 4. I filled out the forms and thereafter was advised there was 1 phone available. A few min later, he then advised that the phone available was actually booked and that I would be contacted when stock has arrived. Little did i know, that this *********** consultant processed the contract renewal, submitted the documents and used the IMEI/ serial number of the phone not available. I have now been invoiced for this phone and being debited for it. <br> <br> I have visited the Cresta branch several times and no one is interested in helping to cancel this mistake by the consultant and further to this that particular constant has now resigned. Numerous attempts of phone calls and emails to the branch manager was made but the branch manager has made no attempt to contact me. I have called the call center and all I get told is that the matter is escalated. Its been 4 weeks now of no response. How can I be charged for a phone that I do not have. This contract needs to cancelled and sorted out IMMEDIATELY.
