Quoted me one amount & bill another? Debiting incorrectly!

I’ve been battling with this for some time! I upgraded my contact based on what I thought was a great deal. I do all my upgrades directly with Vodacom as they are great and usually offer me a good deal. After all, I’m a customer since 1996. So last year, like all the previous years, upgrades due & after much discussions & negotiations Vodacom offer me a good deal, quoted over the phone. I’m not informed that the value added services namely Clip/caller ID & itemized billing is not included! So that’s charged extra on my account over & above the quoted amount. All my upgrades as mentioned were done via Vodacom, so far all quotes included the above mentioned services. I also negotiated my Mothers contract which is under my name and the quote they gave included those services, not specified in the verbal quote!! My brother just did his upgrade which I had a hand in negotiating, his quote included said services!! Above all this.... I get debited an astronomical amount last year June! Oopsie they debited OVER DOUBLE the amount! I’ll add that the debit order notification came through on my birthday! I fell out of my bed when I read the message seeing the amount of over R 4300.00 going out of my already strained bank account!! Then I notice the little extra amounts on my bill which I’m told are the services NOT included in the subscription (repeat: it was never mentioned when I was quoted) Then to add to my aggravation I question why the amount on my Vodacom app is SO much & I’m told it’s an estimate. Now I’m very grateful for the discount on my subscription but this issue with incorrect billing is beyond pathetic. December I was debited over R 1500.00 and this month debit order was over R 1200.00!! The agreed amount quoted: R 949.00 I now have to wait for the credit which I requested go back to my bank account. Which by the way when followed up was set to go as credit on my next billing cycle dispite me requesting that the over R 700 please go back to my bank account ASAP! Now I try to get some feedback and am told my problem has been resolved??? Because you’re refunding me the money you stole?? Yes, stole! I asked you back in July Vodacom if I can trust you, you assured me you would do everything to avoid this from happening again! Debi orders are meant to be convenient & safe, I feel I have to now check every month if you’re going to debit the correct amount!! Not only that, I still have the dispute with the extra services you claim to have told me about when you quoted me! Someone needs to be held accountable for that. You owe me almost 8-9 months of Clip & itemized billing services!! I refuse to be taken for a ride, I refuse to be **********... had you mentioned those services were not included then ok!! But you do not quote one amount then debit a different amount... might I also add the two other contracts I have (was 5 as you know) of which one is due for an upgrade!! Im afraid you’ve let me down Vodacom & I’m damn angry about it. All these years being a loyal customer!! No, it’s not good enough. This needs to be resolved without you repeating the same thing over and over: those services were not included in the subscription. Sorry Vodacom, as far as I was concerned, R 949 was inclusive!! Please fix this!
