Tata Teleservices Ltd — fraud coupons supplied by distributor

I had purchased 4 recharge coupon of 360rs/ in the month of april 21, 2008 but they all are already reedemed. from last 18 months i am trying to resolve my problem from tata. but i got very poor feedback from tata customer services. when even i talked with the customer care they are saying contact with the local help desk. when i contact with punjabi bagh (new delhi) local hub so they had informed me this coupon are recharged from there directly. & as per there manager somebody from there local hub was involve in this case. they will take action on it & resolve my problem but even yet money is blocked in tata teleservices. the customer care even note my complaint in the system. i am also attaching the coupon in this compliant..
