FNB Lacking in Business Support Area

I drove all the way from Centurion to Woodmead to make a purchase only to find that the long queue of people at the business had to be turned away as their FNB provided card terminals were not accepting ANY cards. When I enquired about it, I was informed that it is a frequent occurrence and despite them having raised it with FNB, the problem still persists. I would imagine that in this competitive environment the various banks would be very focused on customer service as well as service to merchants.
