Bad Customer Experience

The customer experience is very bad, the so-called accounts department do not take calls however they make outbound calls. They invoiced me incorrectly R2700 for exams instead of R1800 but guess what you cant speak to them until they call you. I made payment because I need my results and the all that the inbound student services is to send an e-mail to the so-called NOVexam e-mail address and twice with no response. When you contact customer services number 031 it rings with no answer, I suppose they also do outbound calls because they do not want to be "bothered". Someone must take accountability and do their jobs or the institution must employ competent staff. In short I want my 2017 Nov exam results that I paid for, I do not owe you...............this is seriously ridiculous service
