Absent staff... ie ONE bank teller to service the ENTIRE town!

I need confirmation of bank detail. I cannot do this via the ATMs as my card does not have pin activation. This is not activate because every time (and I have tried numerous times over the past months) I enter the local Nedbank branch the branch is packed with customers and few employees. So today I made a special trip into the local branch to request bank confirmation and to have my pin activated. I find that the enquiries counter is now merged with bank tellers and there is only ONE bank teller on duty to service the whole of the town. The queue is at least 20 people deep. It is month end (1) during peak business hours (2) with ONE teller (3) to service an entire town (4). The sales consultants have only one customer to SHARE between them, and the problem is excused by saying that the other bank teller is on lunch. WHAT IS GOING ON WITH CUSTOMER SERVICE? How do I get my bank confirmation detail without switching my bank, although I am very close to doing this. Thank you
