iPhone X availability and then Issues with the phone not resolved despite being sent away

Firstly when I was upgrading my iPhone I was looking for an iPhone X 256GB phone. I was sent to 4 different outlets which I was told had stock. None of them had stock but each time I was sent to a different outlet and the same thing would happen. Eventually I had to take the 64GB phone.

The phone I was given cannot keep the charge for more than 4 hours. With no apps running and without using the phone I cannot get more than 4 hours out of it.

I took the phone in and it was sent away. 4 Days later I got an SMS saying the phone was ready for collection. When I got there I asked what they had found, I was told they "just re-installed the software". Despite the fact that I told them I have done this 3 times. They also managed to break the screen protector on the phone, how this happens when you are installing software I do not know.

So now I sit with a phone with the same issue and will have to take it back in again and start the process again. It is ridiculous that the phone is supposedly sent off to professionals and the best they can do is re-install the software.

Really annoying that I had to settle for a phone I didn't really want and then on top of it I cannot even get one that works. 20k odd for *******.
