GitHub + Branching deployments dont start

since monday no deployments via branching are working. i asked the support (Pro plan) and the only answer i get is can you check it again it SHOULD be fixed. but there is nothing changed so far. he does not looked into our project and this in my oppinion bad answer took about 2.5 days. i answered the email and no response since 1 day. we cant deploy urgent fixes to our Applikation! Who can resolve this problem fast? We need to think about to migrate the DB to another provider now. Help pls.
