Deposit Money Disappeared Into Thin Air

On the 4th of January 2018 I used Capitec banking APP to send R100 to an FNB account. I selected immediate payment and the money was received, same day I then sent R7400 to the same account I selected immediate payment again but the money was never received. On the 5th January still the person didn’t receive the money, I then called the Capitec call centre asking what is happening explaining my scenario they said they do not know what the problem is but they will investigate and get back to me. I felt like that is not enough I then went to Capitec Bank branch (Boulders), I explained to them everything they also said the can see that the money went out of my account but they do not understand what is going on, so they told to wait for 3 working days for them to investigate then will have an answer for me after that 3 days.3 days passed I went back to the branch still they didn’t have an answer for me they said they are still investigating and I asked them for how long are they going to investigate because I need that money to pay bills then they said they do not know, so I should just wait. I asked them how long is it a day’s weeks or months they said they can’t put a time frame I should just wait for their call, remember here I’m talking about R7400. As I’m writing this I’m still waiting for a call that might just be next year… and I have bills to pay.
