We found a favorite service on the Internet, called the "master", arrived quickly, repaired quickly, crumpled and still gave a receipt for payment, the amount is decent. the air conditioner worked for a day and stopped cooling again. the master answered requests to come evasively, saying that there was no time, not today, the site promised only to connect with the master. We are preparing a lawsuit. do not invite these guys, otherwise they will repair without diagnosis and problems will remain.
