MS booking page without administrator

Hi, 

I created booking pages for our client, but im added as a member to those pages meaning, there is no admin who could mantain those pages - they are useless at this point. Is there any workaround how to gain administrative acces to those pages? Usually the creator is also the admin so this is one major bug. Please keep in mind that neither I or client cant just access admin center to change created pages due to security restrictions. 

Thank you in advance,

Dejan
