I paid extra money for a Plus membership and expected to be able to get in at 7 am. Will there be a refund for not being able to get in at the time I paid for??

The hour adjustment is only temporary, it is only to allow associates get ready for increased amount of members they get every day, and provide the members with the items they need, but if you have a concern about the hour you can talk to an associate at member services and they can issue a refund and downgrade you to the regular $45 membership

I recommend speaking to a manager in person about your concerns
