I have Chevrolet vehicle since three and half years, and I'm dealing with Jaidah service center,they have the most professional service advisors, all of them are friendly. but I think the way you deal with them is wrong(or you did not see them at all as you have the wrong number), and the number you are talking about it’s not for Service, and I assure you if you go there personally you will get their working numbers, but the number you have(you got it from Qtel) which is always busy, and this number for all Jaidah Group, which means you did not visit Jaidah service at all.

but trust me they have the best service in Doha after Alfardan, but comparing to a huge number of vehicles they have, I'm sure they are very good.

So I Disagree with you, go check by yourself, and don’t listen to other and when we are wrong we plume the others.

and I'm going for 2011 Tahoe in Ramadan offers they have.

if you like I will give you the right numbers and their manager direct number.

good luck
