SHOCKING BANKING SERVICES

i went into NEDBANK PAROW CENTRE last Tuesday (17/03/2015) to ask for an overdraft on my cheque account that i've had with the bank for more than 5 years. After giving all the paperwork they needed and signing all the documents two days later, I waited another 4 days for a reply. Monday i was informed that there was a backlog at head office but the call will be escalated . 24 hours later (NOW A WEEK LATER) i'm still waiting. Today (24/03/2015) i start getting calls from the same person i signed all the documentation with that they need proof of employment and expenditure. How does it take a banking institution a week to approve a R1000 overdraft yet when you apply for a R50 000 credit card it gets approved withing 48 hours. Don't the little people matter to. This was the WORST customer service i've EVER encountered at a bank - ridiculous.
