No feedback on missing payment out my account

I bought electricity for R500 from our Complexes Electricity supplier’s App...which allows you to make payment via the App. The electricity did not come through, so I bought for another R500 and still it didn’t come through.

I then emailed and called the electricity company and they said nothing was reflecting on their side. They said I should contact my bank FNB which I then did.

I reported this to the bank and they confirmed that the money did go out of my bank account and they will have to investigate and contact the company.

To cut a long story short...this happened in October 2019, it is now Jan 2020...3 months later. I have contacted FNB a countless number of times to follow up. And been told that I would be called by the consultant to get feedback. No one has ever called me. I am just gatvol if having to continuously contact FNB and not get proper feedback on what’s going on with my money!!
