Was I in the wrong for talking to professor about a project group-mate?

In my marketing class I was assigned a group project with two group-mates. We each agreed to do a different task and then they were going to send their parts to me to combine/edit for consistency.

One person sent her part on time (early actually), but the other did not sned her part by the agreed upon date (10/15).

On 10/17 I asked her about it and she said she would send it later that day.

As of 10/22 (our next class period) she still had not sent her part and I had planned on asking her about it during our pre-scheduled group meeting after class that day, but she left early, emailing us that she had a last minute appointment and could not meet that day - so I replied to her email asking for the missing work since I still hadn't received it.

As of today (10/24) I still had not received anything from her (and she did not reply to my email from 10/22 - even though all students are told to check their email daily and she had emailed me from her iphone in the past so I knew she had regular access to her emails, so I explained the situation to our professor who advised us to take over this group-mates part.
Minutes after I spoke with our professor I get an angry email from this group-mate saying how ridiculous and unprofessional it was for me to talk to our teacher and she claims that she did in fact send her part on 10/17, but when I replied apologizing and asked to to forward the original email she did not reply (which makes me think she did not really send it).

How can I move music from my iPhone to my laptop?

Earlier today, I had to do a surprise factory reset on my computer, and before doing so, I didn't have the chance to back up a lot of my data. So, any of the music that I had on my computer that wasn't from Itunes (transferred from CDs, purchased from online shops, etc) can only be accessed from my phone. In syncing with Itunes, all of the extra music on my phone will be deleted. This is okay for now, since I don't need to sync, but I know that eventually I will need to and I don't want to lose all of my music.
All that I can find online is information on how to move music from my computer to my Iphone. How can I do it the other way around?

Can I use an iPhone 5s without a SIM card?

I'm planning to buy an iPhone 5s but I need some help first.

1. Can I set it up and use it to play games, and watch YouTube without a SIM card?

2. If I transfer my SIM card from my old iPhone 5s to the new one will the data appear on my phone bill and say something along the lines of "new iPhone connected" or something?

Can I upgrade my Sprint Phone early?

I went from iPhone to Galaxy in March when I was eligible to upgrade. I now miss IOS and would like to get an iPhone XS Max, but with the Galaxy Forever plan it says I have to make 12 monthly payments before I'm eligible. I was wondering if I could upgrade now and if I can how much extra would it cost?
