They sold incorrect data deal

Good day I am writing this as a sad customer. I trusted Vodacom as a loyal customer I wanted to use Vodacom services only but in February I received a call from Vodacom constant selling data deals. The deal sounded very good and I indicated to her that I am looking for a deal that is going to be daily bundles only as I will be using it to attend online classes and other school work. She assured me that the deal will be 100gb anytime there won’t be night bundles. To my surprise when I checked the balance using another phone I realised that it’s a 50/50 bundles. I tried calling and also writing emails but I was not helped. I called to cancel the deal since it in what I was looking for. They promised to come and cancel the deal l. But I’m still waiting.They told me that they will send ram to come and collect the sim along with the router but it’s been a month waiting for them. They are still debiting from my accounts even though I told them to cancel the contract since they consultant deceived me.
