Communication channels do not work - Supportive NOT

If there was a zero stars I would give it, and apologies for a rambling message in advance, as I am shaking I am so mad. We selected Milpark for my daughter to repeat her Post Graduate diploma of accounting(after reading glowing reviews on their website- obvious to me now, very selective ones). Upon being advised in a lecture that it was time to apply for extra writing time(vitally required for her to pass), she proceeded to start the process. Once I had gotten the form filled in by the psychologist for her(not a 5 minute exercise), she proceeded, weeks in advance to try and apply online. The file wouldn't upload, with no reason as to why. She immediately sent an email to Milpark asking for help(their preferred communication), sending copies by email of everything required plus more, for the application. After a number of days they responded telling her the steps to apply(the exact process that she had just advised wasn't working). She then emailed back immediately, again attaching copies saying it wouldn't work. just to get the same answer(this round about happened a number of times with her getting more desperate). As time was running out, I called their call centre and advised them of the problem(and getting through is no mean feat I might add)- this just resulted in another mail telling her how the upload process worked. After giving up getting help, she tried changing file formats to no avail, and eventually found a tool to reduce the file size thinking it may be the reason she was not able to attach(as mentioned none given), and she eventually managed to submit(this is the advise that was required from them in the first email). This has resulted in her only getting the application in days before test 1 and they have refused to give her the extra time(certain failure), even though the call centre manager spent hours with me on the phone yesterday pleading her case, (the call centre agent I first got through to kept on telling me that she could neither confirm nor deny anything, after which I demanded to speak to management, the only good service received). This has set her up for failure, as her disabilities prevent her reading and writing at normal speed. We chose to send her here at great expense, as she could have repeated at Stellenbosch for a quarter of their fees(R14K) due to repeating, where she also had all her concessions given, in the hope that coming home we could give her the support she needed to pass. She is stuck with them now due to the year already starting, and has no option other than to carry on in the uncaring university that does not read their emails, nor answers their phones, But for anyone reading this, I suggest you find someone else.
