Bad bad bad service

I settled my personal loan last month via the website with my login details. After two days I logged back in and saw that I still owe them around R50 on the settlement. I called them and emailed their customer services with no response to please close my account. The lady said that the account will be closed on the 18th December 2021. On the 20th a debit order went off. I tried 2 hours this morning to get through on the 7th time a gentleman assisted me nicely and promised that my money will be refunded within 24hours and that the account will be closed. I was so frustrated with the consultants services. They request you to hold after taking forever to get through only to be cutt off again. You guys really need to do something, I was very angry after wasting so much minutes on stupid service I received. Really hope to never hear from you again.
