Lying and not giving feedback

Hi I took my phone in for repairs on Monday 20/07/2015 and was informed the service providers line was engaged this was in the morning.I then gave them a call on Tuesday and I was informed Mpho will call me back, he did not.The following day I called AG Mobile myself and was informed the phone is not booked to them yet and that their lines are working perfectly.I called again on Thursday and was informed Mpho is not at work but someone will be in touch soon.<br> <br> This is unacceptable behavior if they can not do it let them inform the customer.I need that phone to perform my duties and this was clearly communicated when I left it there.
