Those certificate Mills as used to be called are well known. Unfortionately I don't know one in Egypt otherwise I'd do it.
The problem is not a concern of these institutions as long as the certificate holder is not entitled to work or further study in these institutions or the entire country, so why they should care.
The blame is on the back home organisations that are fascinated with the degree with no regard to what it means and how it serves their business.
The certificate verification firms are not news. Anybody in doubt of a certificate can investigate it if he realy cares.
