Vodacom is ******* and just adding on contracts!!!!

Vodacom is starting to become the same as the country *******!!!! In June i cancelled one of my contracts and asked the gentleman that helped me IAN is hes name to check when is my other 2 contracts due for an upgrade or when can i cancel it. He told me i can cancel it in end of October so that they don't go off end of November. When i phoned now to cancel the 2 contracts the lady told me it is only due in 2026!! I told her that is impossible how can it be and she told me the IAN that helped me upgraded my 2 contracts for another 24 months.He told me he can reduce my monthly payment until i cancel it in November. Now i need to pay for another 24 months for something i don't want or need and did not give authorization for it because i did receive a Quote but never signed or approved it so they just do like they want and you need to pay!!! I will not pay and reverse every debit order because i did not approve anything!!!!
