Mitsubishi Electric India — Irresponsible Sales Team

I wanted to buy a VRV unit for which I was guided to Mr. Sandeep Seth in Delhi. After speaking to him I sent him my house plan and he committed to revert with a solution within a day. I had been 24 days today and he has not reverted. Meanwhile I wrote him twice to remind him. But he is only asking fir more and more time.
It’s surprising that a company like Mitsubishi doesn’t have any proposable VRV solution or they have hired completely incompetent people who either doesn’t understand technology or are overloaded to sell.
If this is their presales competencies I have my doubt on post sale support
