UNHAPPY WITH THEIR SERVCIE

am very furious with the level of service I've been receiving from Rosebank college and their staff. Early January I enrolled for a postgraduate diploma with the college, buy due to personal reasons, I have to cancel my enrollment for this academic year. I sent an email to their cancellations department on the 30th of January, along with another email to their refunds department, as I had already paid an amount of R12960 for the deposit and R5000 towards the fees. There was no feedback from the institution with regards to the process of my cancellation and refunds. I kept on sending emails and getting different ticket numbers everytime, and a new person would respond asking for documents that i have sent multiple times from the 2024/01/30. I have sent through a cancellation letter starting my reasons, confirmation letter for my account details, my Identity document, proof of payment for the one payment and a bank statement for the other payment, as the payment was done using rosebank colleges direct payment channel. After trying to make contact with the college countless times, today I was assisted by a lady, who told me that they did not receive any proof of payments, I further explained that i sent it through, along with a bank statement. She went on today that i did not highlight the payments on my bank statement and it was not her job to do it for me. I am not pleased with the level of her disrespect cause i tried to explain that my first email did include a transaction history that highlighted both payments. She hung up the phone. What is soo hard about cancelling an application and getting a refund. why do i have to struggle to get my money and get disrespected in the process
