Ignorance and manipulation

I was supposed to install a new tracker on my new car on the 28th March 2023,I had to go to the fitment centre because of personal reasons at home I was given an appointment of 9:30 at Roodepoort,I got there I was told to wait upstairs they will call me and the installation will take 2 hrs ,I insisted on going to the MacDonald across the road for breakfast I waited there for almost 3hrs and they promised to call me as soon as they are done, and never did ..I got there my car was parked outside I was told they were done a long time ago but no body called me.i ddnt want to be dramatic I let it go 2 days down the line I received a call being told that my device is faulty they have to check on it or install a new 1 I was wondering how did it even not work while they took so long and why was the device not tested .the consultant by the name of Linda I /Lindelani to be corrected apologized and assured me all will be fine I should return the car, my question to him was then at who's expense cz I used my petrol and time to go to Roodepoort for nothing .over a mistake that could have been avoided I need my petrol back he said he was going to escalate it .I took the car back to Roodepoort they did what had to be done after I asked the guy about my escalation,he said I was going to be contacted if not I should call and ask for onke or simo they are the right ppl that was first week of April.tll this day no body said nothing and I was never even told about the installation fee .next thing I'm getting debited installation fees and pro_rata fee .I mean what was the pro rata for if the device only started working 1st week if April and 1st debit order was on the 25th April? This is ******* and you guys sell us dreams and do not care about your customers.all you care about is the money not the service rendered.i mean what if something happened to my car while I had a mulfunctional device in it and worse part no body is taking accountability for the mistake or I should say the ignorance.
