Adobe Campaign Classic Business Practitioner Certificate

I enrolled for Adobe Camping Classic Business practitioner (AD0-E329) and installed Guardian Browser but my device which is my work laptop failed to pass system check, I asked the support to help me to resolve the which was unsuccessful, as the result my exam time passed, and I missed my exam. I have raised the ticket with support team to look at my case but no response. does anyone know how we can contact support team (Contact Number). I do not know how to retake the exam
