I can’t. That’s not something we did, and it’s not generally, as far as I know, that’s not something reputable survey companies do. If you say “I’m busy” or “I can’t talk now”, they’ll call you back, but if you say, “Please don’t call me anymore”, or “Take me off your list”, or “I’m not interested”, they should take you off their list and stop calling. If they don’t, try to get ahold of their supervisor or somebody else in charge there and complain.
I don’t know that “opt in” is a good idea, and will, generally, make polls less effective. Polls work by trying to find a random sample of the population. Opt in polls skew the sample, and increase the margin of error of the poll. That’s why if you go to someplace like CNN and fill out an online poll, really the results aren’t worth much. It’s because only the people who were interested in taking the poll took it.
Here’s AAPOR (The American Association for Public Opinion Research)'s comment about the uselessness of opt in polling.

As for calling during sleep hours, generally, polltakers call on weeknights between 5-9, and on weekends between 10-2, if I’m remembering correctly. Obviously, for shift workers and some other people, this will be during sleep or work hours. This is unfortunate, certainly, and if a pollster is disturbing your sleep, then I’m sure he’s not doing it intentionally. The fact is, though, those hours, for most people, are not sleep hours. For the vast majority of the population, that’s when they’re at home and not asleep. If they make the calls at 2 in the morning, that might be the most convenient time for you, but it’ll disturb even more people trying to sleep. That’s one of the unfortunate things about working unusual hours; that your schedule is out of synch with most people, and that affects your life in a whole variety of ways, as I’m sure you know. Being woken up by calls that are, for most people, at a reasonable hour, is only one of them.
As far as not wanting to take the time or interest in taking the poll, that’s certainly your choice, and no one can force you to take it. And, like I said before, if you say you don’t want to take the poll, most reputable polling companies will remove you from that poll list.
