Thankfully I didn't need to use the card right away but they were really good about the whole process - still an inconvenience though. I had to fax them a few things, etc. When I followed up much, much later with the investigator assigned to my case it appears they eventually apprehended the perpetrators but kept it kinda hush-hush since it was possible there were others they hadn't caught yet. Unfortunately, fraud is big $$$ business and we all pay in some form or another.
Just a few months back my Ritz and United CC also fell victim to fraud but it was handled really well - alerts, CSR experience, CC reissue and all.
