No customer service

Day 7 of trying to get hold of FNB i have 3 transactions that i have no cooking clue of where it came from i have been spending bombs on airtime i just purchased R30 airtime which lasted 30min i timed it too the end. Knowing the bank they have time frames fr everything so which means i cant lodge anything for this cause i will most likely hear its past the date to dispute. Times like this i just want to shut down all my accounts and leave FNB other banks have put things in place encase they have any issues most as far as i know all banks are open so why is there no service and technical issues for 7 bladdy days that is pathetic. If i do not get feedback and a solution by monday im posting rhis all of social media and in the new paper and leave people with a bad taste of FNB
