It seems that the promotion has ended. but I don't see my balance increased. When the reward will be accepted by the winner?
As per terms, the competition will run till Sept 30th at 23:59 GMT while now is still 15:00 GMT means that it is not finished yet and perhaps the prized would be rewarded after the closing time. They will need for more few hours, maybe for verification process. So just be patient, if everthing goes well then you will get your prize.
