Dispute form not resolved nearly 3 months later

To whom it may concern, <br> <br> I went in to FNB at the beginning of december to have funds reversed given that the petrol station I use, BP, banked my funds twice. <br> <br> I was told that the funds would be reversed within 3 - 5 working days. I phoned twice as well as went in during January to find out what was going on and I was told there was a backlog in settling dispute forms, however it should be settled soon. <br> <br> It is now nearly three months later and these funds have still not be reversed. This is increasingly frustrating <br> as I am a student and require these funds, as well as do not appreciate the inconvenience of needing to follow up all the time due to a lack in service.
