Unhappy Customer

This is my 2nd time having the same struggle. My car is due for a 2nd service since I had it and every time I have to book I struggle. I called and even sent emails but 5 days later I still don't have any response and my car is due for a service. Even last time I went through the same struggle. Really not happy :(

And on top of that once you are booked you will camp at the dealership the whole day waiting for them to make payment. I honestly don't get it when I always pay on time but they are never on time or there when you need help.
