Still waiting on customer service

I took my new Mokka elegance to the service department as the seal on the right back door needs to be replaced. First the service is absolutely a disgrace.. They booked my car in on Friday 5th of Jan only to get there and waited two ours for them to let me know they still need to order the part. They did not order any parts when I took the car there the Tuesday 02Jan when I came there to ask to get it fixed, no they just booked me in for the Friday and told me it will be done then and still no part. I called them yesterday asking if there is any news in when the part will be here and was told someone will call me back. Well with the bad service I already experience its no surprise that no one has called me back or probably will never do. Its now been 10 Working days since I was there and there is clearly no urgency in their customer services. I do not recommend anyone to take their cars there for services or to order parts. I will rather drive the extra KM'S to another service provider than to use them.
