Failure to understand my issue and being unhelpful

Extremely disappointed with MANCOSA. I'm busy with my 3rd degree with them. The service used to be so good when I started with my BCom in 2013. Now, it seems like they just don't care anymore. If I knew it was going to be like this I would've gone to UNISA. I've logged several tickets, phoned, and emailed and they are either not understanding what I am asking or they just don't care. I got the wrong information from the call center on several occasions. I've also got an assignment that wasn't properly marked and still struggling with the same request since last year November while I'm falling behind. I need to make contact with the dean or principal as I the people I have dealt with so far are not understanding the issue I have and just wasted another 6 months of life "solving" one query. I see a lot of similar situations on this website as well as other sites.
