Bad service at FNB ***** department

Hi I am Phumzile Mnyandu I have reported a ***** case at FNB Alberton branch on the 27 July 2021, as I have received notifications of the withdrawals in my account. The person who assisted when I log a case is Marble Matlagana she said it takes up to 7-10 working days the case to be resolved . On the 29 around 15:38 j missed a call from Andre same time I tried to call back the number but it says the number does not exist. The following day I called the ***** hotline and I told the lady who assisted that I missed a call when I call back it didn't go through. The lady gave me Andre Poole's email address, I sent an email to Andre but he did not respond to the email . I called them on the 12 August I spoke to Calvin he said the case was finalized the Investigator (Andre Poole) who is handling my case will call me before the end of the day. I waited no one called. When I call each consultant is saying different story. I even follow up using the secure chat Natasha said she is escalating my call to her supervisor that was on the 16 August 2021 and she said the turn around time is 48 hours, today morning I secure chat with Natasha again and she said she will escalate again the case to her team leader. Please help hellopeter.
