We ended up getting cell phones (to avoid telemarketers, in fact) with nation-wide long distance in their plans, and when we moved in November, we decided not to keep long distance on our house phone. MCI calls us all the time, and they introduce themselves as “your long distance provider.” My response, since of course it’s my job to answer mystery phone calls, is always “We don’t have long distance here.” The telemarketer apologizes and hangs up. Next time I pick up the house phone and it’s MCI, I will be a little less nice.
