Popi act not followed at akermans woman wonderpark

I went to Akermans woman in Wonderpark to collect laybye on behalf of my mother the cashier asked for my id and my moms and she made copies of them, now i get an sms that my application for opening an account with them is declined and my mom got one that state that the application was successful she must come to the store to procced the with the application. Who gave authority for akermans staff to open accounts without our knowledge and agreement from us? Popi act is not used at akermans that's ***** now our copies can be used for anything as do anything they please with our id copies. I need clarity
