MTN customer services is shocking

Hi I went into MTN Cresta in January for an esim and I was told they can't assist unless I take out a contract with them even though I had an MTN number, I told the assistant I would do that as long as it was a month-to-month contract and I could cancel at any time which they said they would do , I confirmed with them a few times and yes you can cancel at any time. Since January I have had a few calls of ***** and sim swap issues so I decide its to much of a risk I want to cancel. I go into the same MTN cresta shop to cancel to be told we cannot cancel the contract to have to call MTN and do it as there is a cancellation fee as it's a 24-month contract so you have to pay a penalty. already annoyed I say okay this morning I call MTN to cancel to be told after a few hundred questions twice as you get transferred a few times they cannot help me I have to go back to the shop to pay in the cancellation fee does MTN just want to lose customer your service both at the store and call center is shocking and I still have to go in again as nothing is sorted out very annoyed
