Poor service

I've been with Outsurance for the past 7 years and have never made a claim on my insurance policy. Unfortunately on the 30th of April I got bumped and due to the other party not having any insurance cover I had to claim from my Insurance policy. Took my car for repairs at Renew It Randburg and when I picked up the car on the 16th I realized the bumper wasn't fixed properly and there was a space between the bumper and the rubber in my boot. Renew It Randburg attempted fixing the bumper but after using the car for a day I realized the space is still there. I called Outsurance on Monday 23rd of May to let them know the car wasn't fixed properly and so they can speed up approval for a new bumper on their side, as requested by the panelbeater. I have been calling on a daily basis and 4 days later I'm still being sent from pillar to post and I'm still driving with a bumper that's not properly fixed
