Not helping

After I complained and FNB promised to call me they did nothing. If I did not go to the bank and demand my debit order to be reversed I wouldn’t have had my money. The next thing they send an email to say my problem was resolved and they are closing the matter. This is not the desired resolve because: 1. You are taking credit in my own efforts. I took the initiative to resolve it after nothing was done. 2. I am not assured that it won’t happen again. 3. No one contacted me to explain what the problem was. 3. Worst of all no one contacted me. That’s why I went to the bank to revers it myself.
