Cut in on a roundabout from the right lane no indicating. Proceeded to sharp break multiple times because I beeped, even after me shouting I have a child in the car. He then did the same thing on the following roundabout I was in the left lane taking 1st exit he was again in the wrong lane and on his phone pretending to video me, then jumped in front of us causing me to sharply turn to the left and go into the curb.
