Contract upgrade

I recently upgraded my cellphone contract online with Vodacom. When I phoned in, I wanted to cancel my contract but the lady I spoke to offered a good deal and I renewed that contract. The phone was delivered on the 10th of Jan 2018 and the nano sim card was not sent with the phone. I phoned the customer care call centre on Friday the 12th to let them know of this. They said the sim will take another 3-5 working days. Today (22 Jan 2018) when I phoned, the lady I spoke to could't even read that the note was made for the sim card to be delivered. She told me that it'll take another 3 - 5 working days. I'm literally siting with a phone I cannot use. Come month end I'll have to pay for the phone while it's just gathering dust.

Very disappointed
