FAILING TO TAKE ACCOUNTABILITY, CONSULTANTS IGNORING MAILS AND CALLS

I WAS SUPPOSED TO WRITE MY ONLINE SUMMATIVE ASSESSMENT IN STRATEGIC SUPPLY CHAIN MANAGEMENT, WHEN I WAS DONE WRITING THE ASSESSMENT THE PORTAL DID NOT ALLOW ME TO SUBMIT MY ASSESSMENT. I RAISED THIS WITH THE OSA TEAM AT MANCOSA AND THEY PROMISED TO RESOLVE THIS, THEY REVERTED TO SAY THEY DONT UNDERSTAND WHAT WENT WRONG, THE OFFERED ME TO WRITE A SUPPLEMENTARY OF WHICH I DID BUT THE SAME PROBLEM STILL PERSISTED, THIS TIME AROUND I COULDNT EVEN GAIN ACCESS TO THE ASSESSMENT. NOLOYISO ZONDI WAS THE SUPPORT CONSULTANT THAT WAS ALLOCTATED TO ASSIST ME WITH THIS, SHE HAS BEEN IGNORING MY EMAILS AND CALLS FROM AUGUST TILL TODAY, SHE DOES NOT EVEN GIVE ME AN UPDATE ON THE OUTCOME OF MY SITUATION. I CANT BELIEVE THIS IS HOW THE INSTITUTION TREATS ITS STUDENTS AFTER PAYING SO MUCH IN STUDY FEES. NOW I HAVE TO PAY THE FULL TUITION FEE BACK TO MY BURSARY BECUASE OF THIS INSTITUTION FAILING TO TAKE ACCOUNTABILITY.
