Bajaj Electronics — Delay in installation

Address:	Hyderabad, Andhra Pradesh, 500068
Website:	Bajaj electronics.in

I have purchased a Samsung Air conditioner on 17/04/2016. They said it will be delivered next day and installation would be done within 48 hours. Ac was delivered on 19/04/2016 but no one came to installation till now. I am calling the showroom daily. No one answers for sometime then when you get answered they will ask ur contact number and they will try to send today and in the evening when no one comes to ur house u call again they say tomorrow for sure... Is there any solution
