Cannot make or receive phone calls

I dropped my phone 7plus the screen is cracked. I cannot connect with whoever is calling or when I make calls it automatically hangs up when the other line answers. I also cannot hear sound in my recorded videos. Everything else works completely when it comes to sound, I can play music, and listen on my headphones ect. I can however can make calls and answer calls through Bluetooth.

If can anyone help that would be great.

Thanks in advance.
