Go to a Nothing physical store and they will fix your phone just like Apple will in their store. Apple won’t fix it online and to even contact their support regarding technical issues you have to use Apple ID or device SN or any other proof (such as warranty, bill, anything) or they will ignore you. Everyone everywhere knows what to do except some people in Nothing community, pretty impressive.
Edit: To prove it:

Many options to pick:

Whatever you choose you have an option to schedule a repair:

For which you need Apple ID (which is linked to your Apple device, so effectively the same as having a bill in your example):

So no, Apple won’t just keep answering to you like a chatbot as you claim, because you can’t even contact them without Apple ID. No idea why are you lying when it’s all publicly available to everybody 🤷♂️ But yeah, grrrr, Nothing is so bad…
