My Apartment complex had the gas pipes checked for leaks today, October 9th. A notice was posted that we should give our home keys to the 경비실 if we weren't going to be home during the posted hours. I gave my keys to the 경비실 October 8th. Your worker, 정은**, did not even check to see if keys were given to the 경비실. She posted a notice on my door that she had been there and please call her. When I did call her she said I had to be home later in the day or on the weekend to have my pipes checked. If she had done her job properly and checked for keys, there wouldn't have been a problem. I hope in the future you will not inconvenience me again.
