Shocking Service

We took our Datsun go into the TV branch on 4th May for a service and complained about the Driver Window having a winding up/down properly issue. Car just under 1 year old. We had car serviced and when we collected car we were told that it was the rubber of the window and they needed to order it. We took it back on the 20th June to get this window fixed (took them 3 weeks to get the rubber and a further 1 week before I was able to take car in)... Anyhow, on the 20th June, they had the car for the entire day and when I went to collect it, I was told it was the window electronic winder and not the rubber and they don't have stock (they had the car for about 7 hours). Already irritated, I took the car and left only to get home and notice the door panel hadn't been put back on properly as now the door knob and key holder were tight and slightly skew. My husbands branding was also removed when they washed the car. To date, we have even spoken to the Service manager and still nothing. Its been 2 months.

We may only have a little Datsun Go and I am presuming that's why they don't take us seriously??? But really - 2 months to fix a window issue still under warranty?
