No time for clients

I requested an appointment for my MB C55 AMG or service and I was given a date. On the date the service adviser told me that she had bad news for me due the stuff party - they were not going to be able to service my car. She just gave me an estimate for work required and service.<br> <br> A week later I requested her to send a report/estimate to a Warranty company for approval so that she can rebook the car and order part. She failed to do that.<br> <br> After another 7 working days I call her for a follow up and she told me she hasn't done it and she's busy with other clients. Whenever she gets a chance she will try.<br> <br> This is a very terrible service I received from Mercedes Benz - Workshop.
