Its been a week since I passed the CCA175. I received the score card with in few hours (though it took me two days to figure out that I was in spam folder) with pass status and a score of 8/9 . Ever since I am waiting for the digital certificate and the licence number. Tried contacting cloudera support and diligently checking my spam folder regulary. But no luck !
I am sorry to hear you had issues receiving your certificate. Your best course of action is to email firstname.lastname@example.org. The certification team will then look into the incident and reply to you directly.
