I'm not going to answer the phone.
Why wouldn't you answer the phone?
The phone keeps ringing and I'm going to kill someone if it rings again.
If the phone keeps ringing somebody could desperately be trying to contact you. Answer the phone, it's rude to ignore the person calling you.
It's some stupid people who's calling. Piss off.
You don't need to be so rude about it. If you don't want to talk , you can text them to know what they want.
