50% hike in bank charges

I was shocked when reviewing my bank statement to find that my bank charges have been increased by a whopping 50% and this was without and notification from standard bank.<br> <br> I do understand that bank charges need to increased every year but by 50%??? thinks that is more than just steep.<br> <br> I have been a standard bank customer for years actually since the age of 12 but I am really disappointed by this ridiculous hike in bank charges
