If someone interrupts your speaking and shows the sign of impatience or superiority or thinking you being incomprehensible or whatever, what would you say? Is it good to reply

If you are trying your best to communicate, and they interrupts repeatedly which you think is unreasonable, will you say:
Could you please listen and let me finish?
Do you understand how to respect others when they are speaking?
I saw this sometimes happens between some Americans and some foreigners in U.S., either on TV shows or in real life. I personally have some similar experiences in arguing about questionable bills with customer services
