Unacceptable Service

I took my phone in to the Samsung Care Centre to be repaired as the phones touch screen did not work, i was promised on the day of taking it in it will take two hours to repair. The very next day i went in to collect the phone but it was not done as parts have to come from Gauteng. If i was told this on the day that this is the case it would have been fine and i would have made another plan, but it was not.. It is now the fourth day that the phone is in for repair. This is unnacceptable to someone that needs a phone to do business. This has caused a great loss.
