Damelin - Useless

I did numerous courses at Damelin in Centurion which seems to have closed down permanantly now. I am trying to find out if the Project management certificate is approved by PMBOK or Prince but nobody can assist me at Damelin for some reason and they keep refering me to the Manager who is Andrew Gillchrist but he is not responding to calls, mails or on linkedin. I have now sent him numerous mails with no response. It seems he is not interested in his job or clients. It's been almost 2 months without a response
