Yesterday i bought guop coupon of maruti mega mart sector 7 faridabad.
First i joined group then other 4 member joind nd each person purchased voucher for rs. 500 its successful completed eveone got voucher code & cash back for grou comletion i did this around 5.50pm but in eveing around 7:20 or 30 i got msg that due to technical issue your voucher cancelled and refund initiated after adjusting cash back.
This is not fair i created group & people joined me. Magicpin vouchers for rs. 2500 purchased just because of me.
