What upgrade?!?

To my surprise my debit order that went off this morning was more than double than what it should be. I phoned customer care and was advised that there is R150 upgrade fee for 2 of my old devices. Apparently I received a call on the 8th of January for the apparent upgrades. I would like to receive the recording for that call please! I did NOT agree to any upgrade nor have I received any new devices. I was told by the customer care consultant that I need to call the rewards department because they did the upgrade. Someone at your rewards department made a huge mistake or they are just plain ********* and I don't have time to phone different call centers because your employees are *********** or *********. Can someone please investigate what happened and fix my account? It seems like ***** to me because I did not agree to any upgrades and I have also not received any new devices. In fact I would like to cancel the contract on those 2 OLD devices, the sooner I don't have to be a Vodacom customer the better! Please get someone from cancellations to phone me as well. I am going to reverse that debit order and as soon as you have fixed your mistake and my account you can debit the CORRECT amount!
