bad service - rude employee

My watch has been serviced there by a young man. He messed up with the watch and didn't tell me. He charged me first, then I discovered that the watch was malfunctionning and told him. He didn't even appologize, just told me that he didn't have the manual for the watch(!?) Then he said he would fix it if I bring him the manual. Ofcourse I won't come back. Go there at your risk!
