Hey man, my bad, should have mentioned which branch of National Garage.
Its the National Garage at Haji Ali. Man they are unprofessional. It is only when the servicing manager is called that things are done.

Recently paid over 2K just for oil filter & oil change and had to wait over an hour to
give my car for service. There was an elderly gentleman who was waiting for more time than me & i felt so bad for him, he had come all the way from the suburbs. Then called the Servicing Manager (very nice man) & he got things done immediately and the way they should be done (Mr. Cyrus). And this was just recently, in fact, whenever ive gone there for servicing, ive always had a very bad experience.
Also, always have to waste an hour when i give or pickup my car from servicing as the car is never ready on time even though i call and tell them. Eg. ill tell them ill be there by 430 and they say the car will be ready, then when i am there by 435, they say they are getting the car from their parking and it takes like 45 mins to get it and another 15 mins just to make the payment. And this is not a one-off incident either. Happens everytime, have complained but to no avail, so have even stopped doing that.
Another thing worth mentioning is that whenever my car goes there, for any sort of mechanical work, when i get it back, within a week it has to go back for some other job. I feel that they are messing around with the car. Off late, apart from the oil change, i havnent got any mechanical job done by them and my car is working just fine since the past year.
Eg. for this would be when last year in Jan i gave my car for normal servicing (mechanicals involved), the AC was just fine but when i got it back, it wasnt working. Told them about this the next day and they said it wasnt working in the 1st place!!! After that i only know how much time was wasted and how i got it done.
Since then, whenever i give my car, i make sure to get the AC checked by them before i give it and have never had a problem since.
Unfortunately i dont know any other place to get an Opel car serviced, else would have changed the servicing provider long back. Perhaps you could help me out
