Vodacom cancellation refuses to cancel my contract

I took out a 24 MONTH phone contract with Vodacom in March 2021. 1. The wrong phone was delivered to me& i was basically ******* into it without my consent or agreement. (Vodacom shoud have the phone recording of that particular day), tried returning it& i was given the run around& eventually settled for that phone because i had no phone& was desperate. 2. My installment of R173 is now up to R212, which is something that wasn't made clear to me in the initial agreement, i let it slide. 3. We are now in 2023& i've been calling the cancellation department to cancel my 24 month contract& they keep telling me that it end at a particular month, i call again on that month& i'm told a different story. It is now the 27th month& my contract still hasn't been cancelled meaning they're still taking money from my account. 4. Today i call them& they tell me my contract was 30MONTHS!! How? When? i keep asking for an explaination& they just drop the phone on me. Vodaome owes me money& i want it back in my bank account!!
