Bad customer service and time delay and inconsiderate of my time

I took my car in on the 23 Jan 2023 and the 26th i received a call to advise that I will receive an email with a quote for strip and quote so that they can ascertain what is wrong with the car. I signed the quote on the same day and send back. After the 26 Jan 2023 till date no further communication. I called the following week to get feedback and i was advised that they have a backlog, and they will work on my car and after that no further communication. today 13 feb 2023 I went personally to find out the status and when I get there, I am told that the person handling my car has since been dismissed. The lady that completed the form and took my details did not advise me that my file has been handed over to someone. Upon signing in my car, she advised that she will be providing feedback and today when I went there, she is asking me information that she had taken when she opened my file. she tells me that the gentleman has been dismissed due to poor service, so my question was i don't know anybody besides you, did you communicate the process after you signed in my car which she did not. she tells me that she received the diagnosis from the Engineer and that she will give me feedback by the end of this day 13 Feb 2023 and now its 10h14pm and no feedback or email received from flora auto clinic. I asked for the part that was taken out for the strip and quote to be returned and put back and she said no, they have to quote first and only upon acceptance or rejection can they return the part as the engineer its far. 21 days without the Flora auto clinic working on my car and still giving bad service after I have personally went there and told my apologies and we will surely send you a quote and diagnosis by end of business. They are not even offering a remedy to my immobility due to their lack of service. To say I am frustrated it's an understatement.
