Upgrade

I processed an upgrade last week Thursday. First of all it took Vodacom 3 days to phone me to do the approval/authorisation for the upgrade whereas previously they would phone me that same day. Secondly, when they phoned me to do the authorisation the lady said it would be delivered by today. Thirdly, I have not received a waybill number. Lastly, I phoned again to follow up and the lady told me NO it will probably be delivered by Friday and it has only been invoiced now. That is unacceptable, always when I did an upgrade it was done and delivered within 2 days, how can it take 7 days now??
