Insufficient service delivery

I simply cannot understand why it takes this long so sort something out. I have been trying since 7 March 2019 to get this done. Spending endless hours on the phone in an attempt to get this sorted. Today alone 60 minutes on the phone and still waiting. On 7 March 2019 transactions were reversed due to ********** activity. A few days ago these transactions were debited from my account. I again phone FNB and they reverse saying it will take effect in 48 hours. I am still waiting. Please can we get this sorted I have to use my cheque account surely that should be common sense that I need to money to live and therefore need to use my account. Surely!!!!!
