No update on contract upgrade

Over a month ago I had app**** for an upgrade on my Telkom contract and was approved a few days after. I had initially put a delay on the contract upgrade due to the specific cellphone I wanted being out of stock but they then blocked my SIM card due to not receiving payment on a cellphone that I was finished paying for and their only advice was that I renew the contract and take a new phone so I agreed and I was told that the phone is still out of stock. A few days later, I was called and told that the phone was back in stock and that I could continue with the cellphone upgrade which I did. A few days later I was given an order number because the phone was “on the way”. On tracking the order, I would be given a different order number every time which bothered me until I was told by one consultant that I have been given wrong order numbers as the phone is still out of stock. It’s now over two weeks of no update regarding the phone. The only response I get is that stock will be available “this week”.
