Don't bother calling near closing time

I sent an email enquiry to FNB Homeloans 2 days ago with no reply.<br> <br> Today I tried to call. I spent 10 mins from 4.50pm calling and consistently being hung up on or put on silent hold for an indeterminate amount of time until I hung up and called again. Until eventually I was transferred to a message stating that operating hours ended at 5pm.<br> <br> Why bother closing at 5pm if the call centre operators just ignore the calls before that time? That is absolutely terrible service. Why not close at 4pm or 3pm or whenever is a realistic honest time for your lazy employees so that I don't waste my time trying to get through.
