Horrible service and no accountability taken

If I had an option of a putting a negative review I would, I had been servicing my car there since 2020 but the service I received this time around was nothing but horrible.. I took in my car for service on Friday nothing was wrong with my car around 11 I received a call from them as per norm informing me what needs to be fixed on my car again around 2 they confirm the car is done I may come to collect when I arrive I pay the amount due after I am told I should also look into my battery I don’t pay much attention to it coz I know I has changed my battery not so long I go and also battery fault is a build up of which it is not something that just dies overnight. So when I ask for my cars keys so I may go am told they still going to jumpstart the car 1st now that draws my attention coz it is surprising and alarming that I brought in my car without any battery issues now I need to be jump started I express my dissatisfaction, one guy says there is a footage available I request to see the footage of which it took over an hour for me to be able to see the footage even the footage offered does not show everything but where I had left my car when they moved it they was no error and it was moved again without any fault only after they had taken my vehicle in and worked on it when they needed to move it back after they had worked on it it shows lights as if battery is not responding but their cameras apparently do not show the side where it shows the front to be able to see what was actually done on the car ….meantime waiting for the footage I had do experience being harassed by their receptionist. The guy who was initially working on my car promises to get the footage sent to me by Saturday or Monday, Monday morning I sent him a text only to receive a call from the owner shouting and making all threats and refusing to send the footage of which I was promised by one of his employees… now am stuck with the car that has a battery that is basically dead and no one is willing to take accountability but am just being threatened the owner even went to an extent of sending me voicenotes.
