El Centrol College Does anyone even work there? Dalls, Utah

Im in HR and we get alot of applicants that went to El Centro College.  The only problem is we can not even hire anyone that went to school there because no only in that school answers the phone to verify an applicants degree. We contact the registrar's office 214-860-2311 and there main number 214-860-2000.  Actually we've contacted every number on there website.  Same thing happens.  You are placed on hold for 4 minutes because all lines are busy.  Then a message comes up stating their office hours and then the line disconnects.  We've been attempting to reach a real person there for 2 months now.  We even hired a Temp employee to try to make contact with anyone.  For 3 days this temps job was to call someone at their school for 7 hours a day.  With no success.  Cant get anyone to answer and we cant even leave a voicemail.  So basically, its our department decision not to hire anyone thats gone to El Centro College if a degree verification is regard for the job they are applying for.  Sad!
