FNB *****

Good Day i would like to lay a complaint for FNBs poor service. I have reported a ***** case on my account (ID: ***) at the time the balance was at about -600 now it is at -13000. I have received no feedback and it has been close to 2 months. I callled the ***** department to check on it and i was told that the case has been escalated to the cheque account ***** department. I tried calling that same department multiple times but i had no assistance. Yet FNB still sends me sms telling me to rectify the account or further action will be taken inspite of a consultant telling me that they have noted that the account is under investigation.
