REFUND OF COLLEGE FEES - Consumer Complaint for KCA University - Main Campus

Can the management kindly advise me on how long it takes to get a refund after a student has cleared everything? My son cleared with all the Departments and was informed to collect the cheque after a week, he did so last Friday,8th June 2018, unfortunately he didn't succeed as he was informed that the system was down. He was asked to go back today 11th June, he did so & waited till afternoon without success, on enquiry he was mistreated & thrown out by the guards.
