Samsung — Samsung Mobile SCH B259

I had purchased a Samsung CDMA SCH-B259 mobile on 1st June 2009. On the 25th of June 2009 the handset suddenly got switched off and was declared as a dead hanset by the Samsung Customer Care @ Khadki Business Center, Pune. I had given my handset for repair to them on 29th June and till date have not got my handset back even though I have followed up vigorously. I am paying a huge rental for my tata indicom without having a handset to make calls. I had asked for a spare handset to use till the time my handset gets repaired, but they said since its CDMA they dont have spare as the company has not given them. Please help .
