Damelin College - Educor - Daylight ******s

My son was registered for the academic year 2024 at Damelin Randburg. Fees were billed for 10 equal installments, beginning April 2024. I made sure I paid an extra amount every month so I could finish the contract by end of December 2024, whilst my Debi check standing amount was still going off my account. By end of Jan, I only had a balance of R609.60 but to my shock, the debited the full usual debit order amount. Educor has been owing me R2 695.20 since then and up to now, I have been following up on my refund, but keep being told it is in process. I could not reverse the debit order with FNB at the time of incident, as they told me they could not assist me as the mandate was via Debi check and I must take it up with SP. It is now almost 10 full months of waiting and no courtesy of a response or call from them. I have called & emailed Head Office in Durban over 100 times since Jan 2025 and no refund has come my way. They will not even give details of their complaints procedure, nor will they escalate the query. They keep changing staff every second month and always have to start over, re-send documents and emails but same answer is, they have requested the refund. The staff's attitude is very rude, rotten to the core and they do not care about the inconvenience they put you through. They get ZERO stars from me. Can someone advise on how I can get my money back from this thieving lot?
