Is this normal for your voicemail greeting to do?

I have a custom voicemail greeting on my iPhone. I wanted to change it back to the default but before I did I wanted to listen to my custom voicemail greeting one more time before taking it off. When I pushed play it was suddenly a new custom greeting but it was not me and didn't sound like anyone I know. I'm confused and now left wondering how this happen?

No service and searching?

My iphone has recently started saying "no service" and "searching", and I need a fix. Preferably I can fix on my own, without needing to go to Apple. Any suggestion helps.

I have two cameras recording one on the road and one facing me, how do I put the one facing me in a box then the other in the background?

I have a Geekam 4K Action Camera, and I have that recording while I'm biking facing the front of my bike, So it can see the road, then I have my iPhone facing me recording me while I'm biking. I don't know how to put my face in a little separate box, and the video that I was taking on my Geekam Camera in the background. For example, the picture you see with pewdiepie in the little box down there, and then the video playing I want it like that, but instead of the green screen behind him, I just want the video on the iPhone in the box with the video from the Geekam playing on the screen.

Causes of extreme bad luck?

This week my iphone broke randomly then my mothers bed (all I did was sit on it & i'm not overweight) then her china set then my keychain. I don't know how this all happened in one week. Is this a phenomenon or something?
