NON DELIVERY OF 3 COURIERS

Location/place: ALLAHABAD UP

Name of company/service: ARAMEX COURIERS PVT LTD,MUMBAI

Respected sir,
first of all thanks for giving me thus platform.
i recharged my mobile phone online via www.freecharge.in via order id: 16491149(2/7/12 of Rs120),16491086(2/7/12 of Rs 222),16402927(30/6/12 of Rs 120).
They send me coupons of Ms Bikanerwala and Ms McDonald food outlets via Aramex couriers pvt ltd,to reach me within 10 days.
All were having expiry date of 15/7/12.
When none of my couriers reached by 10/7/12,i contacted freecharge.in via customer support;they referred me to aramex couriers customer support .None of the personnel at Aramex customer support answered me how to get my couriers. They told me that courier started from mumbai to reach Allahabad (my residence) via delhi and all the 3 couriers have been delivered to delhi center on 9/7/12.I asked for contact no. of Delhi or Allahabad center of the aramex couriers but none of them gave me even after repeated conversations via mails and phone calls. Now its 16/7/12 and all my coupons are expired and even now courier has not reached me. This is 4th or 5th time of non-delivery ; im complaining for the first time. Can you please help me out??
thanks,
dr vineet
