Urban Company — AC repair

I had booked for AC repair as my AC was not cooling at all. The repair person came and repaired it for which I paid around Rs.8000. However, the cooling survived only one day. After that I booked revisit and the same person came and repaired but the cooling lasted only two hours. I then booked an expert visit however, to my shock, no one came to visit and repair. I need my entire money to be refunded. Pathetic service by them.
