Crompton Greaves / Cgglobal.com — cheated by a crompton dealer

Address:

Kolkata, West Bengal

I have ordered on last 31-may-2017 one 20hp (940rpm) crompton greaves motor from a sub dealer named rajesh gupta, kolkata. As per shopkeeper i have to pay the amount first so that he can send me the product through transport system & i paid rs31100. But when i received the motor it was 20hp (1460rpm). Then i asked him to exchange it. But he is now not ready to exchange because i don't have the prove for previous order confomation. & also saying that bill is made so he cant exchange it. Regarding this i have spoken to company help line no & they gave me a no of kolkata sales excutive no to speak with & named mr ayan chaterjee. When i spoke with him he told me sell that motor by myself to someone else & again buy what i want. Please tell me here how this is possible for me? I belongs to a village area & how many people are using this kind of high power motor.
And the dealer name is rajesh gupta, mob no - [protected]
