Activation of credit card and pin

My new credit card was delivered with instructions to activate it on my FNB profile. Only that was not possible as it was not reflecting on my profile! so I phoned FNB and got it activated. The instruction was to use an ATM in order to change the standard pin provided to my own pin. But that too was not possible as the pin provided by FNB did not work!! and as a result the card was blocked! So this morning I called FNB card division went through a 5 minute rigmarole of authenticating myself, and once successful, I was told to call back later because their system wasoff line! It is such poor customer service to do that. Tell your customer at the onset - dear customer our systems are off line (which is due to maintenance, not sure why that's being done on a Friday 1st of the month during business hours), please call back later. So I still dont have my credit card activated after twice calling credit card division. Tell me why I should stay with FNB? your moto should be "how can we waste your time and irritate you".
