IPhone alarm isn't working?

So, on the iPhone, there's the thing where you'd set a bedtime and a wake up time instead of doing the regular alarm. I haven't been a fan of this thing because the wake alarm options are so peaceful that they won't wake anyone up. But yesterday, I decided to try it. I also set my regular alarms like I usually do. This morning, my regular alarms didn't go off, so I woke up late. My phone ringer was all the way up too. Did the two functions clash? I also noticed my phone was on Do Not Disturb, but everyone is saying that Do Not Disturb doesn't do anything to alarms. Why did my alarm not go off? Any solutions?

Why did Apple delete my iCloud backups?

I had some backups in iCloud from my old iPhone. I came back to get my stuff and it was all gone. My iCloud storage was full, then when I came back it was empty and there were no backups. I DID NOT delete them. There was a lot of photos, videos, messages and contacts in there I will never get back.

Repair company caused a problem to my phone that was not there, how should I handle this?

I took my Iphone 5 to a repair shop to get fixed. My phone worked perfectly, except that it had static in it when I plugged in using an aux cord in the car stereo. I would hear a lot of static. It was like this for about 3/4 months. I had some money to get it repaired, so I decided to take it to a repair shop. They look at it for a couple of hours, and when I came back they told me they could not fix the problem. I got halfway home, only to find out that my phone had no sound. So, I took it back in and told them, I needed them to fix the problem they created. They said, okay leave it with us, and maybe we will get to the problem with the sound. Well, something said call them before I go. So, I did. I called the company, and the guy said, we tried taking it apart rebooting it, and doing something else to it. It worked fine, but then it the whole thing just started to fail. He said, the managers are not here, but when you come back, we will fix everything it is on our end. Well, I called back to find out when the managers would be in the store, and all of a sudden his tune changed to we experienced problems with the phone when we originally started fixing it! I was like no, that is not what you said. You did not make me aware there were any problems with the phone when I picked it up. You did not even tell me that you all tried to get the sound back on. You just gave me the phone back, and said nothing, like the problem you brought it in for we just could not fix. What can I do

Added (1). I just needed to give clarity: My phone had static in it three or four months before I took it to the repair shop. I took it to the repair shop, because I had money to fix it. I could hear my calls. I could here music when I played it. The only problem occurred when I plugged it up to the aux cord in my car to play music from my phone to the stereo speakers. I wanted to get it fixed. I left it with the repair guy. He said, he could not fix the static. He did not know what the problem was.
