Ripping people off during lock down

I app**** for a loan on the 23rd April 2020 and it was approved, and the first installment is due on the 30th of April, because of this fact I decided I do not want the loan anymore as it makes no sense to apply for a loan on the 23rd and 7 days later I must make a payment of a month's interest, I phoned in in the morning today 24th to cancel I was then told that I can't cancel the loan as it has already been processed, I then told the lady that finchoice still requires my bank statement or pay slip for the loan to be completed so I'm am not going to send those since I do not want the loan anymore, she told me that I won't get the loan if the documents are not sent which I was happy with bcz I already borrowed money somewhere else, but just after I spoke to her I received a massage stating that the loan has been paid into my account, R3000 loan and my new balance is already R3455, where must I get this money from, I mean in times like these you want to rip people off their little money.., I WANT TO PAY THE MONEY BACK BECAUSE I DID NOT EVEN SEND THE REQUIRED DOCUMENTS.
