NO FEEDBACK FROM UNISA

MY STUDENT NUMBER IS ***7. I HAD TO PAY FOR RENEWAL OF A MATRIC EXEMPTION CERTIFICATE BEFORE I COULD WRITE MY FINAL SUBJECT FOR MY DEGREE. PAYMENT WAS MADE IN AUG/SEP 2015. I HAVE SENT NUMEROUS E-MAILS FROM MY PRIVATE E-MAIL ACCOUNT, BECAUSE MY UNISA E-MAIL IS NOW BLOCKED, BECUASE I AM NOT A STUDENT ANYMORE. I STILL HAVE NOT RECEIVE ANY RESPONSE, OR MY CERTIFICATE!!! I EITHER WANT THE CERTIFICATE OR MY MONEY BACK. THIS IS UNACCEPTABLE. WHEN UNISA WANTS PAYMENT, AND YOU DO NOT PAY, THEY TAKE ACTION, BUT WHEN YOU PAY FOR A SERVICE, AND HAVE TO WAIT FOR SIX MONTHS FOR SERVICE.....IT IS POOR! I WISH SOMEONE COULD CALL ME BACK. UNISA CAN TRACE MY CONTACT DETAILS WITH MY STUDENT NUMBER I HAVE PROVIDED.
