SAMSUNG give no feedback

The topic of poor feedback & and communication from SAMSUNG: This morning at about 11:30 I received a call that the exchange on my phone was finally approved on day 5 of request - the unit needs to be invoiced then I can collect. I asked that it is VERY urgent and they must please let me know as soon as I can collect. it is now an hour from close of business and I have heard nothing yet - also send two emails with no definate answer on time . No matter how I seriously I said I need it today to some preperations , it seems will have to wait until Monday ?

Can it really take SAMSUNG 4 hours to generate and invoice and let a customer know ?
