Aunathorised upgrade on the other number and refusing cancelation

I Good day

I had an upgrade about a month ago and returned the first phone because it was faulty. They reversed the upgrade. While I was waiting for that to be resolved a vodacom agent phone for a new upgrade but when I went to vodacom with reference number they said they don't recognize it and advised I do it instore now that the reversal was sorted which I did.

A while after that they deliverer the phone from the call with the agent. Only to realize they did this other one on my other number which I don't even use, I never authorized an upgrade on that number.

I couldn't return the phone earlier due to not being around. Now that I want the cancelation and collection I'm told I'm beyond the 14th day period. Seriously times are tough and I have no money to be paying two phones. On top of that on my main number I'm charged more that what was agreed during upgrade.

I really need this other phone collected and canceled cause I won't be paying for two phones, with what money? The phone is still in its packaging untouched
