They also associate by mobile phone number and name matching based on one reply I got to my ticket.
They suggested changing the name on the business account but that would just shift the issue to someone else unless we use a fake name. And I think it did not let me do it when I tried, it's been a year or two so I forget some details.

I did, I can't remember the details but it didn't work. I think it prevented me from adding one type of data because that was already in the other account as a unique identifier (possibly phone number). I just tried today though and it let me add my number, so maybe that fixed it finally.
