Poor Service

Husband has Bussiness account with FNB,they have closed the account even though it had positive balance there is no valid reason as to why they have close. From the 26th of November he has been calling visiting the Witbank branch but no assistance till today. He always go out with an empty word that they will call him. There is no one accountable and responsible to take the matter or assist to activate the account even though he has paid the R500 needed to open it again.
