Very Poor Service, Almost fraudster's. Review on Reliance Digital, Hyderabad

I've bought an LG A.C 1.5Ton 3star from this store on 30th of april, got it delivered the next day. But when it comes to installation they took almost 15 days to install the ac at home that too after a lot of complaints.Ok I could bare that, but what really disheartned me is that the technician just fooled us by installing an old copper pipe that too to a whopping of almost 4, 000 from us.I repeatedly kept telling him that the pipe is an old one, he kept saying no, and the pipe was neither 3m long.I've bought the highest rated, highest price brand new A.C of 40, 000k. It was my dream to get a very good ac at home. I did it. & I also got ready to pay another 2550 for extra copper pipe. He took the money from me but installed old pipe which is in very bad condition.I always had a bad taste for Reliance, so I never turn towards it and finally this time when I given them a last try, they proved me that they are really fraud people.Go for a cheap store in hyderabad but never go to reliance. Please!
