How to get Amazon to stop changing my brand to someone else's?

I’m after some advice on what to do next here to get Amazon to stop changing my brand on my products to a similar spelt brand/company which is nothing to do with me.

My products are Brand Registered, and this change happens automatically and incorrectly I’ve learnt due to what Amazon call ‘brand normalisation” where they remove the common but “special character” in my brand name/trade mark (the &) due to some automatic process. Amazon also makes similar changes such as variations of capitalising the letters in the brand name, which also unlinks the brand, completely automatically overnight and at random. This is rare on any given products but will happens once a year or so on each product. This means all my variations break, as I have products under what the system thinks are different brands, but with different capitalisations and with/without the & symbol. It is as crazy as it sounds.

95% of my products are usually totally fine, but every few months one or two products “break” in this way and my brand name is changed to something else, usually this one other company with a similar but different brand name, and my products then link to their storefront.

Seller Support and Brand Registry Support are useless - they give answers which do not work such as “do a file upload” (does not work as it thinks the products are someone else’s brand), simply edit the brand field (no changes apply for the same above reason), “contact the brand owner to request a change” (I am the brand owner, and simply want to correct my brand and not change it) and several other answers which miss the point. I get the feeling most support people on the phone manage to understand the issue but are stumped in regards to how to actually fix this, and then dish out a template response to close the case. It happens virtually every time.

I have only ever got this fixed the 5-7 or so times this has happened over the past few years by either getting lucking with someone on the phone who immediately corrects the issue after in depth conversations (this has stopped recently, and all cases are written down and transferred to either the catalogue team or brand support, and then closed with a template reply, resulting in useless responses similar to the above), or by emailing the managing director.

I have only emailed the MD once with a clear guide of the issue and they immediately fixed this. I hate to do this and have only emailed them for the second time this time it broke, as 6 weeks on with this issue I have got nowhere this time. A few days on I’ve not heard anything, but I presume this email address gets busy.

There are two questions here - 1) how can Amazon properly stop changing my brand at random and lock it as pr brand registry so no-one and no automated process can fiddle with it? And 2) how can I get my brand back to as per brand registry in the short term?

How would anyone else fix this critical issue, using a method I’ve not yet done? I cannot think of anything else. It is a ridiculous situation, all because Amazon’s systems likes to change the formatting of my very simply brand name. I’m at a total loss really. It really needs a human with the power to act to sort. Any advice for a clear way to simply get the above fixed would make my week. Thank you.
