Very upset

I have been struggling to get my sons account up and running since Feb 2022 after complaints and struggles the account was finally activated and then frozen again. No feedback no reply on emails. I have sent photos of the birth certificate, I have certified the birth certificate. One department says its in order another says its not what can I do to get the account activated so my son can start using his account? This is ridiculous! Please email me as I work in a call center and cannot always answer my phone otherwise phone me between 1pm and 2pm or after 4pm
