Terrible banking systems and service

On saturday the 25th of Jan i tried swiping at the petrol station only for my card to be declined, however there was funds in the account i called into ABSA and was assisted by this gentleman who gives absolutely zero shhhhh about client service, i got so annoyed i did end up getting rude because instead of trying to help with a resolution he keeps telling me what the problem is, a problem which changed 4 different times so i am still uncertain of what the actual issue was...what upset me is i have had 2 incidents with absa now in 2 weeks and do not want to bank with you guys anymore i was asked to swipe several times by your consultant whilst trouble shooting and at the end i was charged severall R10 for transaction being unsuccessful no resolution and had to call my father who is an elderly pensioner to pay for my petrol ... I was promised by the agent that he will assist me with logging a formal complaint and i would be cced in the email but that did not happen so i am absolutely livid about this nonsense
