Shrewd and bad customer service

My car was involved in an accident early April 2019. Logged my claim was referred to Renew-it panel beaters in Wynberg. Drop off and book in car. When I fetched my car, I pay my access and then get asked by the service advisor if she can log a positive review on my behalf on Hellopeter for the service... really how shrewd is that. I go out to the yard see my car and then they can't find my spare tyre cover waited almost 3 hours for it. Left without it as Chelene said she will call me and they will come and fit it on at my place once they found it. Eventually after 1 week follow up calls from me I am told that they have found it but I must come in to have it fitted. I make Chelene aware that they fitted a second hand wrong bumper to my car. I was told the workshop manager will call me and come back to me. No surprise no call. I follow up and call in but no feedback. At this point I return for refitting of my spare wheel cover and find out progress on my new bumper. Wait for 30 minutes and eventually get help from another advisor as Chelene was not in as yet. I was told that Chelene will call me back regarding my bumper. Almost 3 weeks and no feedback or call back. I log this issue with Budget and needless to say no feedback. Are these companies in business to service customers or to rip us off. Reconsidering leaving my insurance company. Oh yes what about the outstanding recording on my laptop claim which is also a month and 2 weeks delayed as they refuse to pay for the claim although they have no grounds. I am referring this matter to the Insurance ombudsman, motor ombudsman.
