I just got a call from this number on my cell phone - have no idea how they got that. I did not answer because I didn't recognize the number and had been woken up out of a sound sleep - 0846!!! I got on here, found this forum and called the number back. A voice message said "press any digit to be put on the do not call list" so I did. Hopefully I won't get "this" call again......lots of others on my house phone, still!!!
Call from "Card member services" to lower your interest rate on your existing cards, pressed 1 to talk to someone, was disconnected. (I now realize I should not have picked up or pressed 1!)
