Unauthorized Contact Upgrade

On the 29th of January I received a sms from Vodacom stating that my request for an upgrade has been processed. I immediately called Vodacom regarding the smses. The consultant suspected that this was an internal ********** act. I requested for the order to be cancelled IMMEDIATELY!He logged the claim and said they will investigate and give me feedback. Two weeks passed still no feedback. I then decided to go to Vodaworld in Midrand with the same complaint, they requested my ID copy and an affidavit. Two weeks later still no feedback, I called Vodacom again. They told me that the documents I submitted at Vodaworld were not on the system, what nonsense is that??!!How ***********. I faxed the documents to Vodacom again. End of February I received airtime which means the contract was active. I called Vodacom AGAIN! They told me the same ****! This week on the 17th of March I received an invoice from Vodacom, for an IPhone 6 and the Uchoose contract. I didn't even have the iPhone they are invoicing for and I requested the whole process to be CANCELLED IMMEDIATELY when the upgrade smses begun! Still my request has not been attended to and NO FEEDBACK at all.
