I called the number on the back of the card (1-800-877-3616) for account information (2 times in case I misdialed), and kept getting a referral message to call 10-15-15-8000. Surprise, a Google search says it's some ongoing international phone ripoff. What's interesting is that instead of them calling and leaving a message like they usually do, somehow they're intercepting phone calls to Kay. I wonder if anyone else has gotten one of these messages from another merchant.
This happened to me on a number listed on a letter from Medco and also a phone number listed on a letter from HSBC on separate occassions. The number got routed to some phone bank in Nevada trying to push a 10-10- system, I don't remember what the last part was but I do remember it being a 10-10- system.
ADD: forgot to mention the punch line, I got a hold of them through other numbers I had for them and when I told them, they told us they will look into it but insisted that we misdialed which I found insulting but I KNOW I didn't misdial. They use VoIP and phone banks that are IP controled (such as Cisco phones) and they don't account that a network change or reconfiguration can easily re-route their lines. This is why most companies have or maintian a strong PBX server inside their own control to avoid this kind of thing.
