[Resolved]  Daikin Air Conditioners / Daikinindia.com — Installation not done

I've purchased daikin ac from amazon and got it delivered on 21 may. I got a message from daikin on 22nd may that a person will come for installation and got his number along with the message. Now the worst part is when i'm calling that number to confirm when he's gonna come to do the installation he's claiming that he's not from daikin and he blocked my number after i called him multiple times. Now when i mentioned same to daikin customer care agents they are giving some vague responses that your issue will be resolved apart from that nothing else from their side.
