UnHappy

A company went into my bank account and took two payments of R8450 + R6500 total of R14950 on the 24th of August 2019 and FNB says they are not able to reverse the amounts because the debit orders were stopped from the company's side. I told the bank that that's an ******* and ******** transaction and they told me to go back to the people who debited my account. I even showed the consultant the messages between me and the company representative. The company said they'll refund me between 7 to 14 working days but I still do not trust that they will. I can't wait till then only to not get my money back. I want fnb to reverse the transaction asap. Its the 26th today and I have to pay rent and school fees.
