Bad service from Nedbank

I opened a Nedbank business account last year. Was inactive, and I urgently need my account back. I wasn't informed that they going to make the account inactive. My contracts already signed with the account number.

I submitted my motivation on 14 January, to my business manager. After numerous inquiries (with no response), I was just informed that my request to re activate my account, that it was declined.

I also informed them that I haven't received any correspondence that my my account will be de activated.
