Do airpods being connected to your phone stop your phone's alarm from going off?

My alarm didn't go off this morning but thankfully my roomie woke me up! I couldnt figure out why because my sound was on and full volume. I also was not on do not disturb which doesn't really matter bc your alarm works with do not disturb anyway! I tried to turn off bluetooth to see if my airpods were getting the sound and not my phone and i did and then my next alarm went off. Was this just a coincidence or was it really my airpods?

I had did a giveaway and I'm getting a new iPhone and Apple watch?

So I had signed up for doing giveaways and I recently come across this page on Instagram that their was this company that is run by Apple and that company is called Apple Union Square. I had looked up the name to make sure it wasn't fake and the company does actually exist. So I had to buy two gift cards ( Apple and Google ) to get the two apple products which is the iPhone and the apple watch. After I had got done with all the instructions they've told me to do, they finally had put both of those apple products and are delivering to my house address.

So I would like and love to know that when I do get the iPhone and watch, am I the one who has pay for the phone, or does the company pays it for me? Because I mean, I don't have $1000 and I couldn't be able to afford one. But I couldn't see how would the phone and watch be payed by a giveaway?

If you're one of those people who have been in the same issue as I have been, I would love it if you please give me some information about it down below in the comments.

The giveaway should be free, right? I mean I just basically followed the directions they've told me to do and I got it done right and so I just need information about the payment.

Thank you for taking your time reading this and I hope ya'll have a good day/night.
