[Resolved]  Sathya Agencies — Defective AC delivered

I have ordered a llyod split 1.5 ton AC, it got delivered yesterday and today they did installation, after installation we came to know the display is not working and complained to technician, he said its has to be fixed by llyod and asked to sign the doc which says successfully installed and its working properly. I didn't gave him the installation voucher, after that i am calling to sathya agencies, they are not responding at all. and when called to llyod they are saying you should call to sathya agencies and get the product exchanged. This was my first purchase at sathya and never thought of this kind of response i will get. please help
