"Please take my number off your list." and hang up. Any company that follows the OFCOM rules is obliged to honour verbal requests for removal, so that's the correct thing to do.
Admittedly, a cold calling company that follows the rules is an oxymoron so I tend to just cut them off with a "for fuck sake", hang up, Google the number out of sheer curiosity, and then add it to the block list. Every now and then I see a number in the call history that's been auto-blocked, so that at least provides a little satisfaction.
Or there's the Google call screening thing, though legitimate callers find it confusing and often hang up before you get chance to take over the call, or assume it's voicemail and try to leave a message.
