Consumer Redressal

I am owner of Samsung Galaxy Note 3 Neo IMEI No.351665068707780 covered under accidental insurance from Royal Green Services (P) Ltd. (company) vide Policy No. 805973. My phone dipped in water and the screen of the phone went blank though the phone was switching on and i could backup data. It was submitted to company on 24th Mar 2015 via job sheet no. 4465. 1st the company told me that my phone is TAMPERED and my phone cannot be repaired. 2nd time the company told me that my motherboard is broken. But there was no physical damage at the time of handover of the phone. 3rd time the company told me that my phone's LCD is broken and my phone is unrepairable and offered a nominal exchange value of the same which i did not accept. Ever since i have been writing mails and calling to their executives but there is no response and no status of my phone is given which is harrassing. Its been 3 months and the company has made no attempt to contact me. I had to buy another phone because of this.
