cancellation not been processed

Took out a sim card only deal. within 2 days I got a better offer then decided to cancel the sim only deal within the 14 days as prescribed by Vodacom.

I have been calling to cancel and to date i’m told that the previous consultant didn’t lodge my cancellation. on the 8th of May a new one was lodged and escalated. I was told it would be cancelled by the 10th and I would get confirmation email/text. Today is the 11th and no cancellation has happened. the call centers wants did another escalation request. when I asked that this is the 4th time i’m lodging a cancellation and the 14 days is running what what is the solution the consultant said he really doesn’t know!

Vodacom why are you own controls not working ? why is it this difficult to cancel an order ?
