Mobikwik — voucher says expired

Address:

Andhra Pradesh

I got a voucher code from crazeal.com worth 59 which gives 100rs account balance on mobikwik.com
but wen i used it in my existing account it says voucher expired
when i contacted them through Facebook on their page
their reply was the voucher is valid only with a new id
then i created a new id and try to use it
but
it still says voucher code expired
then i contacted their customer service through fb but got no reply from them
contacted them even through mail 4 times but didn't get any reply
so please be CAREFULLL before recharging through mobikwik.com
doesn't care customer problems at all

my existing email id:[protected]@yahoo.co.in(mine)
and the new id i tried with:[protected]@rediffmail.com(my friend's)
