Address:

Pune, Maharashtra

As per the offer, if future wallet is loaded then 15% cashback (Max up to rs 300) would be received. Offer valid between 16 to 22nd oct 2017.
Hence i loaded my wallet with rs 2100/- (Transaction id is wt[protected] on 18th oct and purchased the clothes from central-pune on same day.
As per offer i should have received the cashback of rs 300/- instantenously (As per executive from mall mentioned to me) or max within 4 days.
But inspite of continuous followup company has not added the cashback into my wallet.
More important in this company's ethics. Company does not deliver what it promises.
Below are the various complaint ids raised, still no action done:
