Consumer Redressal

I have purchased one bajaj majesty ktx1 travel kettle 0.5 lt on 09-09-2013 from Spencers of Mani square mall, Kolkata. Product serial no. G154 TK02 0313 00089. Within few days, it has stopped functioning. I have lodged a complaint on bajaj helpline no. on 06.11.2013 & got a call no. 3482600-1. As per instruction from them, I went to Applicare, authorised service center of Bajaj (5, Sunyat Sen Street, Kolkata-700012) on 16-11-2013. Request id: u-1200/J. They have told that it was irrepairable, so I have to wait for replacement. Since then, I have made several visits there physically or contacted them over telephone for last one & half years (I don't have any documentary evidence for my multiple physical visits or phone calls). But all my efforts are futile. Today (06-03-2015), I again went there & they told me that no claim I can make after such a long gap & all fault is mine. What can I do now for my harassment??
