FNB Ripping people off #EXCESS Fee

#EXCESS Fee.

I swiped for Petrol, had money in my account at the time and now FNB is charging me an #EXCESS fee for R180.00 because I cant honour the payment a couple of days later.

When calling FNB they say its because the petrol station only put the payment through later, THIS IS NOT MY PROBLEM - I had money in my account at the time of purchase, the money should have been allocated and taken off my account.

I was put through to someone to assist me, waited for 20 minutes with NO assistance and NO reference number given.

I would like my money back as this is a ****!
