Unlock summer entries locked before the draw date

It seems that the entries received into prize draws for the 'Unlock Summer' promotion expire the day before the draw takes place. I have seen this with multiple entries, regardless of the timeframe between receiving the entry and when the draw is scheduled. Based on this the intention would be to make a customer believe they might receive a prize - when they have already been excluded. (Not sure if all customers have looked at the expiry dates.) Yet another reason to make me lose trust in this company.
