Bad Servicet: My car is worse off now!

I sent one of your amazing machines(my car) to Fury Sandton for a diagnostic and a full mechanical test, which cost an arm and a leg, but DID'NT complain as this \WAS THE BEST\". I told the sales person there(Michael De La Rose) the problems i was experiencing. He then told me what the output documentation would look like and that's not what i received at the end! I received a manual(which i was told it would actually be system generated) printout that highlighted ridiculous faults that were obvious for any driver. The document was PROMISED to be sent to me over the weekend but WAS NOT, until i called in and even after i received it, i had to ask for Micheal to tell me about the areas i told him to focus as they were not there, and only then he altered(NO CREDIBILITY), i complained and was referred to the manager ( Silvan Moodley), who then referred me to Woodmead, where Peter gave me another quote which is totally different from the Sandton one. Peter defamed my car (YOUR BRAND) by telling me to get a new car, and now after Woodmead my cars system is faulty and doing things it never did after i took it from Sandton. I trusted your guys to take care of my car but they FAILED ME!!!!"
