BJ's Wholesale Club review: BJ's is a scam with fake promotions and hard to use discounts

Terrible experience with BJ's membership and customer service. I received a promotional postcard from BJ's to join for $15 and receive a $30 credit after first purchase. The card was validated by the local BJ's Store and I signed up. I was given the rules for qualifying for the $30 credit (spend $90 or more on one visit within 30 days). Two days later I spent $184 on groceries at BJ's, but never received the $30 credit. I went to the local stores customer service desk and they said I should have gotten it. I called the 1-800 number for BJ's customer service and they looked up my account and the offer code used. They told me I should have received the credit and it would be processed within 2-3 days. I never received the credit so I called their customer service again and this time the representative told me I would receive an email from their rewards department while I waited on the phone. Five minutes later she came back and said the matter had been resolved and I should open my email. The email from BJ's said in one sentence, we have reviewed this matter and the discount code you used was rejected and there will be no credit given. I closed my two week old BJ's account on the spot. I had used the promotion they sent to my house, it was real and valid. BJ's is a scamming people and no one should shop there.
