Upgrades department

I have been calling numerous times through to the Vodacom upgrades department and honestly say I am not happy this time round! Saturday 16/06/2018 I made a call to continue my service and try see if I can get my upgrade before my birthday but after speaking to a agent at the upgrades department and advising it was approved, did i not receive a call from the confirmation department on delivery or the agent to inform me that there was a issue on the system. It is now the 27/06/2018 and still no luck, even though now i get a call from Tshenolo from customer care which has been good with feedback but almost two weeks now, really guys?!
