Poor service, company run by ****** and *****

I have been a loyal client of vodacom this company is run by a bunch of ******. On the 19 December 2022 I was called by a sales rep who **** to me saying that he will migrate one of the plans on my vodacom profile in a way that will allow me to get more data instead of sms nd this will cost less. He **** because when I saw my invoice the migration costed about R200 more. I called vodacom cancellation department immediately to request cancelation, I called numerous times to confirm cancelation nd they promised me that they canceled it and to my shock on 31 December 2022 I get an sms saying my migration is processed. I called again nd asked why they haven't canceled I was not given a clear explanation and what shocked me more was that they actually migrated me to another plan where I am to get R500 airtime per month which I didn't agree on. Now I have to pay extra when I requested cancelation immediately and I even have to pay for something I didn't agree on. This is foul play on another level.
