Address:

Ghaziabad, Uttar Pradesh

http://www.freecharge.in/ invite people to get their mobile recharged through their website and in turn promise to provide free coupons of same amount. The take Rs 10/- extra for sending the coupons through courier.
I recharged my Mobile(Service Provider: Idea) for Rs 350/- on 12th of july 2011. The SLA is that the consumer would get the free coupons within the next 7 days.
Its been 18 days now i haven't got my free coupons yet. I have posted on their my complaint so many times on their customer support section but to no avail.
Attached is the screenshot you of their customer support section.
Can anybody tell me how to escalate it as they do not have any support contact number mentioned anywhere on their site.
