Urgent- can't submit results Alevels

So I have tried Soo many times but my portal has some kind of issue, it just does not work!

Tall me some place where I can contact them other than email because I have no clue what to do, I tried emailing​ the 4 times no response!

I need a contact number or something where I can schedule an on-site appointment and submit a hard copy.

Please help tomorrow is the last day.
