Disgusting service from FNB

On the 26th or 27th of May 2 debit orders went of my account without my authority, I called FNB on Thursday to reverse it, spoke to a lady who authenticated me and then put me on hold for over 15 minutes and the call got cut, I called again same thing happened. Got so upset I left it. I called Friday , I spoke to a gentleman who I told I was made a fool the previous and he clearly did not care , I went through the process again from Thursday and I was put on hold and the call eventually got cut. I called back , waited on the line and then got to a consultant who answered the call and kept quiet and then acted like she cannot hear and cut the call and I know this and I know this kind of behaviour from experience, I then wrote a complaint on the complaint site FNB. The lady called me today and advised she was helping me, she put me through to the department that she said is going help me, I waited on the call for over 30 minutes and the call got cut, so even the complaints department is *********** , so now how do I GET MY MONEY BACK ?
