I didn't receive the voucher yet but I definitely sold the required amount.

i take it you definitely received the offer for this promotion via email? it isn't applicable to everyone - only those who were offered it.
if so, i'd contact support either via their live chat or by email / phone and tell them about it and they should be able to correct the issue and send you the voucher :]
