Edutel with their *********** service

I'm registered at Edutel for advanced certificate in foundation phase. Last semester I failed... and did not qualify for exams. I re-registered the modules this semester wrote my assignments and passed. But all this information suddenly disappeared from the system when it time to write my exam they are telling me that I did not register for this semester and also they are using last semesters results to proof that I don't qualify for exams. This is so draining I was supposed to write math last week and English tomorrow. There are not helping me I even sent them screenshots of online assignment submissions but they are not helping, insisting I'm not registered. Funny because my busary paid for this semester's and I wrote all my assignments and passed. I am irate and frustrated.
