Poor service-No answers regarding marks

I had a mark on my portal since 2016 till today that mark from there it didn’t change, suddenly it reflects as my 2020 mark; I keep being told that my matter has been sent to the examinations department. I requested my marked exam paper, was requested to pay and I did but, to this day I have not been given my marked exam paper and the 2016 mark is still there. There is no way of escalating matters or getting assistance from anyone at Mancosa, I am being given the run around.
