Costco – Customer not happy, closed vista card when paid in full

We were told that the card was closed just because it expired, we called and gave them the phone number, address everything they need, we had to call costco to get a membership number we already had one it got closed, no warning or anything, but yet they call him. he was good about payments they wanted to start credit again, they lied to us saying that it was just closed because it expired. so paid membership card and told it was open then when using it isnt.
