Refund taking more than 4 weeks to resolve - WHY??

main person dealt with Ra-Ina Badenhorst Accounts Manager. First enquired about request for refund on the 11th of April, one of the staff in admin or reception advised that I send an email with my request to Ra-Ina, after no communication from anyone I then contacted IMM and only then did someone advise that I need to submit a form, and that the form is on the website. The form was not on website and in fact had to be sent to me. When it was eventually sent I sent formal refund request on the 14th of April to Ra-ina, who only responded to me on the 16th of April with the refund form attached, this is after I had already sent a form. I sent reply to her on the 16th to advise I had sent form already. To that mail she only rep**** 5 days later on the 21st to advise that she'd received form and said it can take 30 days for refund. No explanation provided as to why it takes that long, because funds are in my student account. I sent email again to Ra-ina for feedback on the 28th of April, to which she only responded on the 13th of May to date no refund and no explanation into why a refund of my funds should take over four weeks.
