[Resolved]  Hitachi — window AC malfunction

I have purchased a 1.2ton Hitachi split AC from Great Eastern Trading Company, Sreerampore branch on 03/03/2013. The AC has been installed on 21/03. The AC is not providing any cooling. The service centre at Sreerampore is saying that they will not provide any service since that machine has been installed by someone else. But those men were sent by the dealer since I did not call anybody for installation. They took Rs. 2500 for installation and Rs. 900 for 24 ft drainage pipe and did not deliver any money receipt. In the scorching heat of end March the expensive air conditioner has become a show piece.
Nothing has been done till date i.e. 10/04/2013. Today I called the Srirampore service centre again. They are asking to report to the dealer, The Great Eastern Trading Company, Srirampore Branch or the head office of the service centre. Since they have not done the installation they are not interested in providing the service. The numbers from which calls were made for the installation are saying that they are masons, tailors etc. I don't know how they could get my phone number. But the customer care executive told me from their record that Ramprasad Gupta had done the installation.
