First time buyer unpleasant experience

I went to the brackenfell branch in July 2021 I purchased my first ever car, I went to collect the car on the 1 August 2021, when I got there the back window was supposed to be replaced and a full cleaning of the car had to be done, the window did not work past halfway and the car was still dirty and dusty, the wheel alignment was off and the tires was placed incorrectly, I took the car and organised that they come collect it in the following week to be sorted, at this point I was still understanding about everything, I sent it back the following week and when it returned to me two days after, it had so much scratches and ditches in the car, and none of the problems was done, the window still didn't work, the tires and alignment was wrong and it also came back with my bonnet handle broken. I then emailed customer care for support and I received one call to organise a date to discuss the problem as they didn't know why they were calling me, then I went in on a Saturday to speak to higher management and they were not there, I spoke to the receptionist and he gave me a email of the higher management, I emailed him and found out that it was a **** email. End of story I never heard or received any feedback again. So this is my last resort.
