Review for Costco – Very Disappointed I left Costco feeling upset and disappointed. I had created and paid for my membership through the app, but when I got to the store, they wouldn’t let me in because the payment showed as “pending.” The customer service rep, Jasmin, claimed she had refunded me two days ago so I could be charged again—but I never received a refund. She said if she charged me again, I’d have to come back in person just to get a refund for the second charge, which made no sense at all. On top of that, her attitude was rude and unprofessional. She spoke to me with an ugly tone in front of other customers, which was embarrassing and unnecessary. I canceled my Sam’s Club membership to give Costco a try, but after this experience—I’ll never go back to Costco again.
