I cancelled my card in January but was afraid of something like this happening. JetBlue can't even get their own website functioning on a daily basis. How can we expect them to get a major credit card conversion right?
I called Mosaic in January after I received a kit from Barclays AFTER I cancelled the Amex. I was livid. They told me another data dump would happen before people started getting converted in March. Looks like that didn't happen properly.
I'm not sure that JetBlue can legally share card member info with the bank if they even have full access to it. That sounds like a PCI compliance issue to me. The data should have passed from Amex to Barclays. Question is when was it pulled and sent to Barclays. It should have been pulled within the last 2-3 weeks not months ago.
