Never leaves a message.  Constantly calling home number

They called while I was at work and when I called them back, all it said was "Thank you for calling the General Readers Service main line." And then it hung up on me.

This number calls my cell phone while I am at work. Getting more and more of these types of calls that never leave a message. Now when that happens I add each number to my cell phone book and assign "SILENT" as their ring tone ID. No more interruptions!!! YAY!!

They called my home line.  I don't take calls from OH lightly.  Whatever called left no message.

this was the best call i have ever had.
they had some great news for me. Im glad i anwsered my phone. thank you.

Had "great news" that I'd been entered in a sweepstakes and was eligible to win $25k and will be receiving four years' worth of free magazines - supposedly people are entered if they use ANY credi or debit card. Tried to make some jokes about the weather. Asked if my address was correct, then wanted to know my age, at which point I stopped the conversation. Scam.

More of the same! Called during working hours; left no message.D
