Vodacom

I initially took out a cellphone contract which was suppose to be for 24 months at R350 monthly. I paid that amount for two months only when I received a call stating that the plan is no longer available therefore it will be R400. Debit orders would go off and it would be different amounts. Long story short my contract ended up being longer than three years. I phoned March 2024 to find out when exactly is my contract ending, I was told to phone April 2024 to cancel my contract. Which I did then I was told I had to pay end April, end May and again end June. I paid at vodacom store and they couldn't assist me either. I was told my account is settled. I checked vodacom account and shows my account is in arrears but yet vodacom can't assist me once again. It is damn annoying paying the whole time but can't get any help!!! Vodacom is the worst ever!
