Closed my bank account with out informing me

Today I got paid. Urgently need to pay a few accounts. Logg onto my internet banking but it does not work. Phone Nedbank. They have closed my account due to it not being used. I open the account in October 2015 but only managed my pay to get transfer to this bank account for January 2016. As was at the bank on the 8th of January to get proof of bank account from Nedbank. Now my salary has been pain into this account that has been closed in the meantime. They say it will take 24-48 hours for them to give me feedback if they can reopen the account. <br> How the hell to you close an account without informing the client. <br> Not happy with Nedbank at all.
