Poor Quality Repair Doine

We had our car repaired after a small fender bender. On collecting the car, we found that a fog light had not been fixed and the service from the repairer was very bad. Contacted Out surance who reassest the damage, only after we sent them the photos. When the light was replaced by a different repairer, we saw that the bumpber had not been repaired property. Sent the evidance to Out surance who just keep sending back the second assestm,ent. CAN SOMEONE PLEASE HELP AS THERE ARE SEVERAL ISSUES Thank you
