FNB is a *****!!!

FNB is honestly ripping us off! I checked my statement and found that on the 30th of November they deducted R150 for #item paid no funds which I didn't even understand what is was for and who gave them consent to deduct money. On the 1st of December i deposited money into my account for my fridge debit order. On the 2nd December I check to see if they had deducted the money for the fridge, the debit order bounced because FNB deducted my money AGAIN!!!! For #Item unpaid no funds. Guys how am I honestly supposed to pay my debit order if you are doing this. At that time I'm not even working. I lost my job due to covid. This is utterly wrong. I'm going to close my bank account with FNB today and I want my money back
