Spice Jet Airlines — company has used my voucher

Address:

Delhi

Dear sir,

I Rishi Narang had traveled to Srinagar in 20 June 2010 against Pnr -U1IQCG. On the way back on 25 June we waited for our flight for full day at the Srinagar airport. In the evening they told us that flight is cancelled neither they pay for ou hotel bill for that day. On return on next day they anounced in the flight that each passenger will be given Rs 2000 voucher for there next journey. The validity of that voucher is till December 2012. Now I had come to know that my one voucher has been used by a passenger name Mr. Deepak Joshi
his Pnr - I78GBC.When i called up airlines they said your one voucher has been used and i dont know this passenger at all. The airlines had used my voucher i want want it back for my next journey.Kindly look into the matter as i had mailed them several times but airlines is not calling me back.
Voucher no. 17546867 Passenger name Mr. Deepak Joshi travel dates 27 December 2010 return 31 December sectors Delhi - Srinagar

Thanks

Rishi Narang
