Ask support to recover the super administrator user

Question

Hello Supporter,

I'm from Cambodia. ACLEDA University of Business(AUB) got a Microsoft O365 product through Softline Cambodia company, which helped us work with Microsoft to get the O365 system to support teaching operations at AUB. Now we face an issue: we lost the super administrator user. When we lost a super administrator user, there was some feature we could not configure or set.

Can you help me get it back?

Thanks and Best regards.
