400% price increase in safe-deposit box rental

Ned bank has not rep**** to my previous complaint, so I have reposted it again<br> <br> How does Nedbank justify a 400% increase in the price of their safe-deposit boxes? I was paying R290 yearly for a small box and now receive a letter informing me that the new price is R1160.<br> <br> I can understand a moderate increase of 10% but 400% is absurd. Yet again the banks just fleece the South African consumer.
