Vodacom has no regard from the truth and it's management has no integrity

I upgraded my cellphone on 24 July 2022 for a package that is R399. When I received the invoice it said that I would be paying R473,01. I immediately called Vodacom to query it and I was told that my previous contract expires in December.

A Vodacom consultant advised me to pay R370 to settle the price of my previous device. I immediately paid the amount of R700. Upon calling again I was told that I should have gotten a settlement quote from Vodacom which I was not told in the beginning.

One of the consultants I spoke with, Oscar, told me that he spoke to his team Leader, Kedi Saletse, who would call me the following day to rectify the injustice that Vodacom had done to me and return my payment to the agreed price, R399. Kedi didn't call me as promised, I tried to get a hold of him/her to no avail. Vodacom has now fixed what I need to pay and it is not the R399 that I was promised. Vodacom has the worst service ever and no integrity whatsoever. I regret upgrading (renewing) my contract with them.

I still need Vodacom to remedy the situation or cancel the contract once and for all.
