Slow System Update

I went into Bayside branch yesterday to update my surname (as i got married last year) the lady helping me kindly assisted me with the change. As i have misplaced my cheque card i wanted to order a new one (but with my new surname obviously) but the call centre advised that they cannot as it still reflects my old surname, they told me to call 24 hours later, 24 hours later i call (as i really need a cheque card) and I'm told that it still doesn't reflect and to call back before COB. I cannot do this as i have a job and even took leave to sort this out yesterday at the bank which seems was a waste of time. How can it take so long for a simple surname to be updated on your system? I need this card ordered today (with my new surname), i do not have time to keep calling the bank only for them to tell me the same thing over and over.
