No correction as promised

I wrote a complaint on 11 March 2020 (see section below). A few days later an agent from Vodacom phoned me while I was traveling. Could not take his details. I explained the problem and he said he will investigate. The next day he left a message on my cell phone that he will cancel this upgrade and reverse all extra charges. Received an invoice last week, no corrections were done, and new account is close R130 more.

Call agent misleading promotion On 5 March 2020 a person phoned me offer a new option on the data we have on the contract. She said the call is recorded. Please listen to this call as my instruction to her was clearly that I am not paying more than we are paying now. She promised me that the bill will be reduced with 25% on the data charges and we will get additional data. She said the rest of the contract stays the same. I made it a few times clear to her that I am not paying more. My daughter is using this phone and on 10 March 2020 she received the following message: “Great choice! Your bundle was loaded and the data was prorated for this month. You will receive 3GB on the 1st of every month and R172.99 will be added to your bill monthly. View your balance …..” This is misleading and I instruct Vodacom to reverse this misleading deal with no cost effect to me as the person who did the deal **** to me. Current bill R541, new one according to Vodacom Irene is R656.70. Was expecting a decrease not increase as per the promotion.
