ABSA bank ripping public off!

ABSA banks are ripping the public off! R10.00 admin charge if you Accidentally enter wrong pin, purchase declined and then 5 seconds later enter the correct pin, and purchase approved! Unacceptable charge from ABSA! ABSA say they won't reverse charge!! Although amount not high > it is the principle {imagine they do this to 1000 people - nice sum ABSA make???) - they already charge a hefty service fee for doing nothing!! 'Very easy to enter incorrect pin if the retailers machine buttons are hard to push or pin area very small!' Not good customer service ABSA!!!!
