If it involved breathing, talking to a bot would be a waste of your breath. The bot can’t actually achieve anything, except pointing you into the Help.
If you want to cancel streaming memberships, you can do that for yourself; though if you didn’t subscribe directly to Now, you need to do it on the website of whatever company you subscribed through.
If you want to cancel broadband and move to a new broadband provider, you should let that new provider know, and they will normally deal with ceasing Now Broadband for you (but check).
And EE couldn’t move you onto their service while Now were still holding on to the line (unless you went FTTP with EE perhaps). So maybe it’s just that Now need to realise you have gone, and they will refund you.
Or Now think you are still with them, and are pumping broadband down a defunct line, in which case they need to be told you are gone.
Anybody no longer in contract with Now though, either needs a new provider to tell Now that, or you need to tell Now yourself, or they will just keep providing Broadband, and billing accordingly. The Broadband does not stop just because the contract has ended.
Anyone still in contract may also get an Early Termination Charge when they move.
So, bottom line; if your new ISP, if any, hasn’t told Now you are leaving, then you need to, and it can’t be done via a bot, you have to call them.
Which you can do by calling 150 from a Now landline, or take your pick of:-
