False advertising by Vodacom

I'm so disappointed with Vodacom, I took a contract with the lm in March 2024, I initially wanted a Samsung phone but the consultant convinced me that the Vivo Y28 is just as perfect and more, and yes I'm happy with the gadget, but the guy sold me false information, when took this contract I already had a another one that I'm paying for so when we spoke the total amount tha t we agreed on was R380, now 2 months down the line the amount changes to R697, when I enquire I was told that it is not the case this is the actual amount I need to pay... I am so livid because nobody is giving me proper explanation, Vodacom agents especially the contracts department are *****sters 😡😡.
