Missing many employment opportunities

I graduated from the Mafikeng Hotel School in July of 2017. I did not, however, receive my certificate. The service provider (CATHSSETA) that is supposed to do the printout of the certificates has been giving the school and myself the runaround since even before the graduation ceremony . The lady who is allegedly responsible for this printing, keeps asking for documents that we have sent to her on numerous occasions but still does no deliver. I am at my wits' end as I have already lost out on a few employment opportunities as a result of this. This is extremely frustrating. Please Help.
