When my local JoAnn's store refused to accept my VIP card, I contacted the corporate customer service first by email:
http://www.joann.com/joann/common/contactus.jsp I was going to give them a few hours before calling them, but before I could they emailed me and said they would speak with the store manager... and then I got a phone call from corporate customer service and the woman was very polite and stated she had spoken with my local store manager and there would not be a problem with me using the card in the future. As irritating as local JoAnn's managers can be, I have found the corporate customer service people to respond immediately. If you don't get through to the number IrelandDragonQuilting posted, try my link (different phone number) because that is where I got immediate response. Also, when I was living in MA and I returned a defective craft table to my local Joanns for a refund/replacement. The tables were sold out. I was told I could wait until they got another shipment in a few months or take a JoAnn's gift card instead. I took gift card. Hope their policy hasn't changed since they were recently bought out!
Good luck Vicki D. I hope things get resolved fast!!!!
