Nissan Parow I need my car!!

It’s really disappointing that anytime I need something from Nissan Parow it’s never simple and easy. They’ve had my car for repairs for 5 days now (including the weekend). I was told 2-3 days but the manager said he would try to get it to me in 2. I understand not being able to fulfill that but when the 3rd day comes and goes a courtesy phone call to let me know there’s a delay and when my car would be available would be great. So I take initiative and call and I get put on hold by the receptionist, she takes me off hold and asks again what I want and puts me on hold again. When I finally decide I’m done with her excuses and hang up I get called back and told I’m rude. The incompetence of this dealership is actually unimaginable. I’ve read numerous complaints from other customers and it seems like nothing is being done. Can I please be informed about my car. Is it ready for pick up? The service agent who I dealt with said she would call me when it’s ready but I find out today that she’s on leave till the end of the month.
