How can I find out when my phone will be ready for pickup after repair?

So we still haven't gotten the shells in, so it- Oh, your phone hasn't been worked on yet. So, once we get the shells in, your phone will be able to be worked on, and once it's done-

We're waiting for the shell, which should be coming in before the end of the week.

Yes. Okay, thank you.

Once we get the shell, we'll be able to work on the phone. Once we get the shell, it'll take about a day.
