Poor service upgrades

i upgraded my Vodacom contract online on Friday 28 Sep. I received an email this morning mentioning they were going to deliver my phone today. This was a problem as I didn't have my documents ready so they couldnt give me the phone. Fair enough. However I should get a days notice to have all the info ready. Another issue was all messages were being sent to another line , not the actual one being upgraded. this is very frustrating. When I phoned the call centre nobody could help me or even understand my issues, I was pushed between customer service and the upgrade department. Please address this as this is very poor service.
