iPhone 15 PLUS

I ordered a iPhone 15 last week Thursday and got approved but all of the sudden I get a sms that’s saying the iphone 15 plus is out stock meanwhile when I had ordered it last week they did not mention that it’s out stock they told me a courier guy will update me.all of a sudden the phone is out of stock how? I’m absolutely disappointed with the service. Honestly wouldn’t recommend anyone to have a contact with MTN!
