Tired of Vodacom's arrogant service

I am seriously trying to cancel both my contacts I have with Vodacom, one is due for upgrade. I recently upgraded my other, but since I upgraded this contract I have been paying for a phone I don't even have in my possession due to technicalities on the phone since I got it. When I upgraded this phone, the lady advised I could cancel the other contract beginning of December, and will be no further money deducted in January for this contract, but the other day when I called Customer Service as no one is getting back to me, they told me it is only due for upgrade but not cancellation, Customer Service adviced my complaint would be escalated on Friday 13 December 2019, it would have taken 24 hours for them to give me feedback, till now still nothing.

I have called complaints and customer care and have sent mails several times now, and I am not getting any joy.

I have been a loyal Vodacom Customer for more than 11 years, and what have I been getting in return, just poor service. 5 years ago my account was charged over R 4,000 for data Vodacom claimed I used. I mean really, a person always hear of these people being gifted a awesome new phone by their Service Providers for being such loyal customers for a certain period of time. Not once I have been rewarded like that from Vodacom for my loyalty, and at this point, I don't want anything free from Vodacom if this is the poor Customer Service you are living up to.

I will be making my Voice heard in more than one way, I have had a enough of Vodacom's arrogance
