Misselling of a data contract

On 26 May 2025 I received a call from Vodacom Upgrades and the lady that spoke with me said that if I upgrade my data contract, everything will stay the same and I will receive more data. Today the 6th of June, I tried to buy airtime on Vodapay and Banking app but i couldn’t. I contacted Vodacom customer care and I was told that the upgrade that was done on my two contracts doesn’t allow airtime topup. I was told that they can do an upgrade reversal but it will take a month. How am I supposed to stay a month without having airtime? I’m always on the road and should something happen, how will I contact my insurance or call for help? I’m hurt, angry and disappointed. I want this upgrade reversal to be done immediately.. the lady who did this upgrade for me was not truthful and **** to me.
