FNB: Appalled and Disappointed.

I called in for assistance to request for my business account extension date for end of August 2020, were i spoke to two business consultants for my extension and they assured me it was done for end of August. Came the 29-30 Aug i went to the bank to make a payment of that outstanding amount, i was told the account has been already closed i can't make a payment. So clearly these two consultants (Bianca & T Gumede), deceived/misled me as a loyal customer. I'm truly disappointed and appalled by the service and treatment I received from the FNB stuff. I need this matter to be resolved as soon as possible, because its been more 14 days i still have no response from either one of consultants. I sent emails to T Gumede to make follow ups but it seems my requests fell on a blind and deaf ears.
