Wrong Amount of Loan

To whom this may concern, on the 5th November 2015 I app**** for loan of an amount of R5,000, the lady that was helping me told me that my application was sent to the creditors for some review, and then 10mins later I got an SMS saying an amount of R29,500 has been deposited to my account. She then called me immediately and told me it was a system error I'll need deposit the whole amount back, and which immediately. But now the problem I'm sitting with the account that is still opened under my name, and initial charges that the bank wants me to pay. Can this issue be resolved because this was not my mistake and I shouldn't take responsibility.
