I came to their office today, it WAS CLOSED during working hours! I called the specified number, they said that the guys were on the road, then why specify working hours and invite them to the office if no one would be there...
I live in AKTOBE, while on a business trip I stopped at Gazcenter, which is located in Astana. I've been planning to put gas equipment on my car for a long time. The guys are all young, knowledgeable, while I was relaxing right there in a comfortable room with a TV, I was working with the car. I liked the service, the equipment is guaranteed for one year.
