Having a contract with Vodacom

I need help. I am a Vodacom customer. I have been using this cell number since from 1999. But my problem is with regards to recent contract i had with Vodacom.

In 2020 March i parchase a bargain of two LG devices at Vodacom shop in Cape Town Zevenwacht Mall in Kuilsriver. I was receiving an airtime on those two devices. On March 2022 my contract was ending and i visited the store to give notice that i want to end a contract once i finished with my 24 Months. At the shop they couldn't help me as they said they dont deal with the cancelation at the store, they gave me acontact number to call the cancelation department. At the cancelation department i was told that the contract cannot end as the last payment has not yet reflected on their side. They said i must give them some few days for the money to reflect on their side.

Few days later when i go again to the shop they gave me a number again claiming they can't help me, i must lodge acall myself . I called vodacom and i was told that they are unable to end my contract because after certain date the airtime and data has already loaded to my phone. This happened for three months doing ups and down. Until i stopped the debit order. After the debit order has stopped i experience a frustration of my device being blocked. I have been paying huge amount of money in order to access network again.

I tried to end contracts i have with Vodacom but seems still difficult. Now they told me that the other number there is an upgrade on it of which i never authorized that. I don't want contracts anymore with vodacom.

Please help
