WORST SERVICE EVER

My car got bumped last month on the 7th September the lady who helped me report the claim was very helpful and really helped me through the process. However after everything was sorted and I expected a call from the panel beating company within 24 hours as specified everything came to an halt. I've learnt that the person I was in an accident with actually does have insurance and failed to mention this to me, I've also since learnt that Budget insurance has been trying to get hold of me. I am a customer for almost two years and fail to understand why No one could email me call my next of kin or try my work telephone number as I have continuously mentioned that I do not have signal at work. It is now well over a month and my car is still not fixed I'm not sure what is going on or what is the next step all I know right now is that I might as well not have had insurance on my car which mind you is a fairly new car. I am very disappointed in the level of incompetence and disregard for clients! One thing is for sure once all this is sorted and (thats if it gets sorted) I will definitely be changing insurers.
