I completely symphatize with their salary but that doesn't mean they would forget about manners specially if we are paying for it..I am not generalizing, some are nice though..and i bet there was no use to send complain because the second call i receive was from an arab guy on the other line, the first question he actually uttered was "what is the problem now?" (maybe it sounds nice to others but not to me). Seemed like the call center forwarded the complain to the branch concerned. I don't think it should be a problem if they are having loads of orders every minute, they can always stop taking orders if they cannot deliver. Another thing is that our job site location is in lusail area, i can say in the middle of nothing, we ordered because that's what we understood by "Delivery service". We understood from their explanation that after the order has been placed, the hotline service forwards the order to the nearest branch which seem to be before the Qatar University. They delivered already few times before. The funny thing was..they noted the mobile number used, to have QR150 minimum purchase next time before they deliver to this caller. So we did little trick, called them from another number with different caller and they delivered. Not having the the "QR150 minimum purchase"...pretty unfair i believe.
