Spending Limit Trouble

A while back I deleted the account that was the parent account to my family link. I don't remember any details about the account except a vague memory of parts of the username. I am not able to access the family link page or change the spending limit, it just says to refresh and that it won't load. I believe it is because of a technical glitch, where the system tries to access the account but can't because it doesn't exist anymore. Looking for help for resetting/getting rid of the family link feature so I can edit my spending limit. Literally a way to just link it to a new "parent" account would be great. I spent an hour with the chat support and received no help, and am feeling confused and frustrated.
