@Carol08Maybe the 4 EZP was just for the hour???
I have no idea since I pretty much never pay attention, but I know Macy's advertises sales all the time where the price changes during the day - you miss the timing of the sale and you're out of luck. You pay a higher price!
I'm not sure why one rep could give you the 4 and another couldn't, but I do know they;re all working in different places and probably get very different information or just never see all there is to see.
Years ago a friend worked for a large organization in a huge room where there were over 500 CS reps working. I'd bet my last dollar that they didn't all tell people the same thing as the person working 5 phones away from them.
And now, with lots of CS reps working alone in their own homes???? - when I don't like what I'm hearing, I hang up and try again with a new rep! Haven't had to do that yet at QVC, but did it just with week with AT&T - first rep was totally useless.
