Negligence from FNB & Old Mutual

2nd Dec 2024 I attempted to withdraw an amount of R4000 from a FNB ATM using my Old Mutual money account card and the atm proccessed the transaction but no money came out though I receive a withdrawal notification. A while later the atm requested I select a lesser amount and I opted for R3000 and that amount I received. I then rushed to an Old Mutual branch to report this matter and I was told to come back the following day to check how the process of investigation goes. 4th Dec 2024 at the Old Mutual I was informed that they are still busy with the investigation and I shall get the outcomes after 30 working days. 17th Jan 2025 I contacted Old Mutual only to be informed that they could not complete their investigation because they (Old Mutual) could not get any correspndance from FNB and I'm negatively affected by this issue at this time of the year.
