Unauthorised upgrade on your account - watch out

On 30 October 2020 I was in contact with Vodacom about cancelling 1 number and upgrading another. The number I wanted to upgrade could only be upgraded in November so she couldn't help me, although we discussed all the options. I was undecided about whether I was going to take a phone or an ipad with that upgrade. I phoned again on 25 November to do the upgrade only to be told that an upgrade had been processed even though I had not authorised it. They processed a contract only upgrade even though I wanted a new devise, so now I can't get a devise. The call was supposedly escalated to a manager to phone me back. I'm still waiting! I tried again on 9 December - still waiting! Today I called and was told that even if they can fix the problem its only going to be from 31 December. So now I have no phone to give to my daughter for Xmas! And the number I wanted cancelled - that's right. Not cancelled!! Two more months of payments made on a number I'm not using, and surprise surprise - it can only be cancelled with 30 days notice. What terrible service! Sadly I'm locked in to Vodacom on all my other devises, but as soon as I can - I'm outta here...
