Pathetic service, 30 days to receive refund

I am a third year student, on the 14th of March 2022 I made a cash payment of fees for the whole year after I was told that my company bursary did not make any payments. Last week Friday I was told by my company that payment was made to Mancosa on the 3rd of March 2022. This means Mancosa received double payments from me and my company. I phoned and spoke to Ronelle Mungaroo who was helpful at first, she told me to send proof of payment from my company which I did, she responded by saying that she has sent it to the debtors desk for allocation because on her side only one payment is reflecting which is the cash payment I made. Today I phoned her to follow up, she was very rude and rushing me off the phone. I phoned again and I was told she is handling the case and refunds take 30 days. Mancosa has been sitting with both payments since March and they said nothing to me until I enquired about it. Now I am told to wait for 30 days for refund. Pathetic service
