WORST NATIONAL BANK! FINDING WAYS TO NOT HELP YOU!

Dear FNB please help me understand what has gone wrong with your services? For many years I've been very happy with your service. Now it has literally gone to the dogs. I have to be on the line to your call centre every damn day it's frustrating how am I supposed to get anything done? Since last night I have been unable to use mobile banking. Apparently I need to verify my browser, which I did with the OTP. I'm able to transfer intra-account but cannot transact. Can't buy airtime, pay for my son's swimming lessons (which are today) or e-wallet because whenever I try to do those, I'm asked to enter my card no. and pin which I do HOWEVER it says it's wrong and I have two attempts left. I call the call centre, put through to the security line with the very card no. and pin I'm authenticated!!! I've messaged on Facebook, no response. No response to emails. I cannot go to a branch and wait over 90minutes to be serviced (this I know because I've been to a branch several times regarding cellphone banking which is still blocked even though I entered correct pin). What foolery is this?
