I really admired the expertise of the assigned technician for he knew the best techniques to address the problem. It was Vadim who fixed our unit. So happy that he was the technician I hired for he fixed it excellently within an hour. He also tried to observe it while working to ensure everything was fine, and if in case he could still find the problem, he would do the repair again. Unfortunately, it was functioning back to normal without problems occurring. The quality was really satisfying!
