2 upgrades failed in one year......So Fed up with my upgrades being changed by Vodacom personnel!

I cancelled my upgrade last year in October/November (under correction), as my upgrade agreement was changed by vodacom's personnel, without my consent or knowledge, after I agreed to the deal that was given to me on the day via phone. When I received my package, I received one S21 and not the S21 plus another phone as per agreed to. When I called in to query it, I was informed that first upgrade was cancelled and new one created for only 1 x Samsung S21 Phone. I cancelled the upgrade, sent back the package and kept my current contract as a month to month thing. Feb this year, Vodacom online called me with another deal but I was not that interested in the expensive deals. I did ask the consultant if he had deals with something similar or exactly as the contract I have at that moment on their system. I agreed on the deal where I got 2 x Hisense Infinity H40 phones for the price of one. Never had a hisense phone but I was looking for a new phone and the extra phone was perfect as I wanted to give my mom a new phone for her bday later this year. I also asked the consultant to make sure he keeps my package the same as I have at that moment...airtime, data etc and he confirmed all will stay the same. I did asked him on more than one occasions if my package is exactly as my current one and he confirmed my minutes will be the same. I did not even think of my extra data deal as that was an extra charge on my account, it was not incl in the phone package amount. I received a msg yesterday with my Vodacom bill and oh my hats! Being charged for a second sim card, which I do not know of or have activated at all....But wait.....Vodacom downgraded my free minutes from 200minutes to 50minutes!! Oh and my 5gig data, which was added to my contract as an extra cost, was removed! Im paying over R700 per month now with less minutes and no Data and a paying for a sim card I dont use or activated!!!! What a **** upgrade ****!!! I called Vodacom customer care this morning and asked for this to be checked and rectified. The lady could not assist me and said only the online upgrades department can help me. I have not heard from them as yet. Prob wont as they are too ashamed of what they've done. I will NEVER upgrade anything with Vodacom EVER AGAIN! Had my 1st cell phone nr since 2000 when I was 16 and I still have that nr today on a pay as you go, from Vodacom. I got my first contract nr early 20's....and this is the kind of service I get for being a loyal customer year after year for 20years+ ....never missing payments.... Definitely time to cancel all contracts when contract time is up and move over to another network.
