Samsung Ac 19wka — Repair not happening

Address:

Uttar Pradesh

I bought a Samsung AC 19WKA on 30/03/2008. Till last Monday it was working fine. On Monday 22nd March 2010, when I switched on my AC, there was some sparking happened inside it. I called up Samsung Customer Care on Monday morning and i was told that their executive will give me a call and visit my place to repair it within 24 hours. Since then I have called them up 4 or 5 times and everytime i get the same reply. Even my explaining to them that it is a very serious issue and my house can catch fire had no effect on them. I don't know what to do now.
