Urban Company — Literally irritated by the service provided

I had called professional from urban company for my ac repair.Professional arrived and my problem got solved.But the same month the problem arose again..i got a free revisit..everything was fine now again just after 10 days the problem has occurred again..i called 2 professionals both of them asked me to call the one who repaired my ac before and he is unavailable these days..I literally feel helpless and i regret to go for urban company..My ac has stopped working and the professional is unavailable..Will never go for urban company in future!!!
