Frustrated is an understatement

I did an online upgrade on the 27th Feb,just before 12h00.I thought this is going to be simple,was I wrong,its before the end of my previous 24 month contract So I didn't get next day delivery and only received the phone on the following Monday. Which is no fault of mine, so I then got the handset on the 02nd March. So I thought that due to my upgrade happening before the following month is would kick in, which it did not... so I got billed the same amount I had been billed for the last two years,BUT I did not receive my 500MB of data as always do.It was a promotion Data bundle for 24 months of 500MB. So I didn't receive that as usual on my account for my last month which is March.On Tuesday I then contact Vodacom from roughly around 09h30 am.I then started to enquire when my new contract will be activated,how to activate the nano sim card and then why I was short paid the 500MB. The first issue was I got sent from pillar to post, literally got sent to 9 different people.Upgrades tells me that the phone is still on back order,I have the phone,Cust care cant see my upgrate on the system. I am beyond frustrated!Some things have been resolved,phone is workin,but acc is now incorrect
