Poor service

I am really disappointed and fed up with Vodacom. I had a contract with them since Dec 2001 for 24 months and it was 2 phones for 1 special.According to them it was a 36 month contract which only ended in May 2024 last month they changed and said its only ending this month. To my surprise when I made payment on the 4th of May I was advised that Vodacom upgraded my account without my consent and that same day I called Vodacom and told them I'm not interested in it and they must cancel it before they load it.I called 3 times and every time I was told that upgrade was pending. Today I was told that upgrade was never cancelled. My phone was also ****** a month ago and I requested that they blacklist the device and son so how can thwy even sent the data and airtime to a blacklisted number. I'm sick and tired of Vodacom I will not pay seems like they don't even know the difference between a upgrade and a cancellation. I'm done with Vodacom for good
