FNB eBucks failure (issue still unresolved)

It has now been 6 days since FNB has rep**** to a hellopeter complaint I logged on the 12/11/2019, informing me that they have notified and logged a complaint on my behalf to the relevant department. I have not received any type of feedback or any form of communication since. I even posted replies on the original hellopeter complaint with no replies from FNB. (https://www.hellopeter.com/first-national-bank/reviews/ebucks-failing-miserably-***)

Last Thursday I took it upon myself to call the relevant department (ebucks) to get feedback. I was told that the team leader, whom it was with, will call me or give me feedback before end of business day on Friday. Needless to say there was none. I even called ebucks again this morning(18/11/2019) just to be told that I would be contacted.

So what's next? Cause I am willing to go out of my way to return the 'favour' for FNB. May some kind of blog or Media house to spread the word of FNB's lack lustre performance and inability to resolve problems? Or do I keep complaining on Hellopeter. Let me try both.
