Poor Customer Service, No Customer Care

Worst customer service received, I took my car for it's second normal Scheduled Service yesterday 11/02/2020. I receive a call to collect it at 4:30pm, I enquired whether everything was in order and my Booklet was stamped and signed and the caller assured me that all was in order. I got there and in my car was my Booklet with no info, last year I had to send someone a day after the service to have that book stamped and signed. So yesterday I walked in and got it stamped& signed because I was still around and it was just after 5pm (which is there closing time).NO APOLOGY received

As I drove home yesterday my car had this weird loud sound that you normal get at s****yards(from loose metals). I pulled over and sent an email at 6pm stating what my issue was, I still havent received a response.today 12/02/2020 I woke up early and got to the branch, was told that the air filter was loose and the bolt was not there. Issue got fixed and all I got was here's your car, is it OK and Byee "NO APOLOGY received for driving more than 50Ks for a second time for a fault caused by their stuff, the fuel I spend and my time. I should have been at work early today instead of being early at their branch
