Brand new car- Engine malfunction and other issues

Very disappointed, I had bad service from when my car went for first service. Firstly my car went in for it's first service when I fetch my vehicle another customer reverse into my car in the service bay at Mazda dealership they only informed me in the afternoon when I fetch my car. not Mazda not the other customer reported the incident at the police. I had to take a day off work to sort out the mess. And had the cheak to say I must claim from my insurance they not liable but my car was interested to them. So I loose and have to claim to have my car fix.Now, in the last 8 months my car was in 4 times for engine malfunctions and they couldn't find the issue on various occations. Some how they fix it on the last enquiry but now I had to manually open my car with key as remote won't open my car and when I press the start button car don't start , I have to press open on my remote when in the car before I can start the vehicle. This is the first time I bought a Mazda thought it was such a beautiful car and still do but, now after vehicle issues, poor service from dealership no curtosy car , I truely will consider another brand with my next vehicle purchase. Still experiencing a faulty vehicle through lockdown.
