Upgrade -Confirmation calling missing in action.

How difficult can it be to upgrade your line with Vodacom! Call 135 on Monday, security check done, upgrade done. We were informed that we will receive a confirmation call, and delivery is between 2 and 5 days. No confirmation call on Tuesday, call Wednesday again to follow up, retention department will send a message to confirmation department. They called in the afternoon we unable to take call because we in a meeting. We call back, you can't call the confirmation department directly, we were told that we will receive a call today at 8:00. Thursday 11:30 still no call, call retention department again, they will send another message, we must just wait. Really is this your level of service? We have 5 lines with Vodacom! Why is it so difficult to arange the confirmation call, even after all security checks have bewn done, this system makes no sense. How long will we wait for the delivery now??? O but don't forget the upgrade device cost have already been added to our monthly bill!!!
