I agree with pberrett--1000 miles for a dollar is a good deal. However, you're actually paying more than that.
Have you ever used your MCI calling card to place a call? I did last year--quite a few calls, in fact. When I got the bill it was well over $200 and I flipped. I switched from MCI that day and Never went back.
My husband's family lives in Europe. When we called there on MCI, we were paying about 95 cents a minute. Speaing with their customer service (after a 10 minuet wait), I was told that to get lower phone rates, I'd have to switch away from receiving miles.
I'm with AT&T now, not receiving miles, and happy in my phoning. I'm also able to get AT&T customer service on the phone after a minute or so, and no shifty pressing this and pressing that in order to get to a person.
