Typical poor customer service from Nissan agents

I took my Qashqai for a service on Wednesday the 2nd March, and asked them to have a look at the suspension as it creaks when I turn and at my left electric mirror as it presses against the bubble and window when I close them in a parking area. I was phoned by the service consultant and told that the bubble is loose and this is causing the problem with the mirror and if they should remove the bubble for me. I told them to leave it. After I got my vehicle back, I found that the right side bubble is a bit loose next to the mirror, but that can't affect the left side mirror, can it? On Thursday I phoned the service consultant Channe-Lee, but her phone stayed engaged. Then I tried phoning Riaan Smith, the service manager, but he apparently was on lunch. I e-mailed him explaining the issue with the mirror and how to go forward in resolving the issue. Up to today I have had no response from him. I work with my vehicle, so I can't sit at home without one every time I need to take it back and they always want to keep it for the whole day. THIS SEEMS TO BE TYPICAL CUSTOMER SERVICE FROM NISSAN AGENTS.
