Bad or Poor service

I have registered with Mancosa late 2020, I never head from them after I was appointed a guys called Thuso Dladla. I picked the NQF level 7 course instead of 6. I have been sending emails to Thuso Dladla who chose to ignore my emails and disregard me. I then called other branches because I needed to know if I'm accepted or not, that's when I was told about my mistake we agreed that he will place me on the right course and update me. I have been writing to both their email and Thuso Dladla. I am so frustrated I don't know what to do in order to get their assistance. I need to know if I am accepted or no so that I can prepare for my studied. I have never received such a bad service
