Do cancel the card.
yes - Sears used Citigroup (I think) for their card administration, and with the diminishing returns on Sears cards, Citi took it and turned everyone’s into Master Cards.
I called the cancel-my-new-card number on the new card they sent, then cut up the card (Did you know you can get more than 50 pieces of plastic outta ONE card!!!) (But you have to be moticated! ;-P)
I think ‘moticated’ is going to wind up along with ‘series’ and ‘hugh’ pretty soon.
Did it already. I only got the card originally (years ago) to take advantage of the no interest, which worked out great, and never used it again. But when they sent me an unwanted and unneeded MC, I canceled. I had only kept it originally because Sears is a great place to shop for major purchases.
I got a Mastercard in the mail from a store account that I had cancelled years ago. And I cancelled it good, with a letter requesting, and a letter confirming. I still have them on file.
So when a unrequested Mastercard showed up at my house, issued by GE Financial Services, I called and asked them what the heck was going on. They told me that the card was issued on the defunct store account, but if I did not want it, it would cancel itself if I did not use it for thirty days.
Hoo, boy, was I steamed! It turns out I had just ordered some big-ticket GE appliances, which were promptly cancelled. Idiots.
