School website flagged and blocked as "Alcohol and Tobacco" by Sophos

I came towards Sophos Support Center for the following reason: our school's website landing page is flagged as "alcohol and tobacco" and thus blocked by some networks using Sophos for protection (and this is not a pretty sight for parents wanting to visit the website of a school facility). Can Sophos fix this issue by categorizing us under "Education" (i can give details in private message so you can check us out to make sure that we really are a school) for example, or is there something we can do on our part for our website not to be flagged and blocked this way by Sophos ?

Thanks in advance.
