Hi, a couple days ago someone bumped into the rear of my car. I was stood completely stationary at a give way and they hit me from behind. It wasn't too high speed so there's cosmetic damage to the rear bumper. We stopped at the side of the road and rather stupidly, I only got their phone number and name. They replied to my messages for the next 1 day and acknowledged it was their fault and agreed to pay but now seem to have blocked me. What are my options? I know it's my fault to not get any further details but is there any way I can do anything with their name and contact number?
