UNRESOLVED COMPLAINED

I have been banking with FNB ever since i was still at school till today. Recently the bank is giving me problems. On the 31st of July 2018 R2 000.00 was withdrew from my account without my knowledge. i told myself that i will go the bank and do the reverse but again on the 5th of August 2018 the sum of R3000.00 was withdrew from my account I discovered that in the morning of the 6th August 2018 when I was checking my app I did not receive any SMS. That day when I arrived at work I phoned FNB and tell them about the problem. The person I phoned e-mailed me the form to fill in and asked me to go to the bank to ask for my statement and to go to the police station to do the affidavit. I asked for a permission from my superior and I was allowed to go. when I came back I emailed those documents to them. The responds I received from them was not satisfying . I then took the matter to Ombudsman for banking services. I sent them all the documents I have sent to the bank and their responds. they said they have contacted the bank after a week and their finding is that I have withdrew those monies. I was still not happy about their responds I went to the bank again to ask for the statement , the statement I got is no longer the same as the one I have sent it stated that R3000.00 was withdrew on the 31st of July 2018 and there is nothing showing about the 5th of August 2018. I phoned the Ombudsman and Maggie the administrator said I must sent that statement and their responds so she can sent them to the person (Manishka Moodly ) the Adjudicator who was handling my case. Till today I have not received any responds from Manishka or Maggie.
