Vodacom won't let me cancel my contract 😭😭

Hallow

My issue with Vodacom is that they are making it super difficult for me to cancel my contract. At first I went inside the shop ad I always do and I was told that they don't do cancelations anymore but I need to call them on *** which I then did, I am not sure if they cut the call or they pretend not to hear a customer. Ibtried several times in different days and eventually I got through. To my surprise the Agent said to me I cannot cancel mt contract over the phone but I need to go back to the shop and call from the shop because my number if flagged... Someone tried to do something with it... Red flagged so they will need someone from the shop to make sure I am the real owner. I went back to Vodacom, called from the shop (Cresta Mall) but same thing happened where the call was nit going through ***, when it did, it got cut. I played this game until I was tired and the Consultant had to assist someone else. Since October trying to cancel my contract till today and they are still debiting my account 😭😭😭😭😭😭😭😭😭 I regret being their long standing customer honestly, not aure if this is how Vodacom operates now. I have just signed up for a Wi-Fi contract with them which I now regret coz I might face the same issue again when trying to cancel

PLEASE HELP
