call waiting beeped on Saturday while talking to my grandmother about my critically ill father. call wouldn't click in.called the number back, but it was busy.
repeated phone calls over the last few days on my unlisted land line; even when i answered, no one said anything;
last time, after about the fifth call, I said, stop calling this number--i know if you receive unwanted solicitations and you say, do not call me any more, or stop calling me o something like that, they are supposed to quit
