Poor Service Aramaex

I have received TWO sms's to say my parcel will be delivered between 8;00 and 17;00 (Friday). IT IS NOW 19:11 and the status reads " parcel will be delivered next BUSINESS DAY?" this is BUL****. I have cancelled all appointments for today and FOR NOTHING!!! when is Next business day? Monday? So I have to arrange my planning AGAIN?
