Poor Service

After being given a contradicting information over phone and secure chat I decided to file a formal complaint on the 3 July. Thereafter was promised that a consultant will call back within 24 to 48 business hours. They had until Tuesday by close of business to call back. Fair enough I waited and even gave them extra one working day. I'm still waiting. FNB promises one thing and do the opposite. May I should just switch banks and close the account.
