R3000 withdrawn by a ghost from my account

we sent an email to dispute querying R3000 that was withdrawn from the account and we were taken from pillar to post to cut the long story short we went to FNB Pretoria North and wanted to speak to the consultant who assisted with the dispute form and was handled by Fiona who told me she needs and affidavit and since I worked for FNB for 9 years I know exactly how the process is , we went to SAPS and gave her the affidavit that she wanted it was in May and told us it takes 6 weeks for the respond and I didn't argue with her and waited for her to come back to us it is now full 2 months and weeks since we waited for her to give us feedback even today im still waiting everytime when we call she is busy we leave messages only her and the people we leave messages with knows why cant she call us back <br> I need somebody to assist us on getting the R3000 back please, and someelse must deal with this matter
