Poor service from Nedbank.

I app**** for a personal loan on the 2323rd of December 2019 and since then it was a struggles to get it approved. I called the call centre on the 30th December to cancel the application and while on the phone i received an sms saying it was approved and will be paid out.but now i didn't want the funds any more. Now i was informed that i have ti settle the lian as they can not cancel. The amount has not even been paid in my account yet. And i was also informed i have to pay interest as well. I dont understand why there is no cooling off period to cancel an application. Am very disappointed with nedbank and their service.
