Hi
I used to receive reward points when i do any transaction using icici card, the

Reward points is maintained by a company called payback (Based in bangalore), i

Have accumulated 32, 000 + points, last week on july 9 2016 i receive an email

Aying 20000 points will be deducted for which i will receive a voucher from

Hopper's stop, the worth of the voucher is rs.5000, also using this voucher i

Cannot purchase any item as per my which. My complaints are as follows

1) how can they force me to buy in shopper stop, that many items cannot be

Purchased using this voucher, so they are forcing me to buy useless items which is

Not sold??

2) how can i receive the voucher without my permission??

Please get justice for me

Thanks
