DISAPPOINTED

I am utterly disappointed with the service i have received from vodacom as a first time customer so long story short last week 30 august 2019 I app**** for a contract online eventually called to contact center and was advised that my application for the contract has been approved however there is no stock in the phone that i want , which i totally understand . I was also told that i would receive a email with my tracking number in order to track the parcel this was not received on the day and i am still waiting . I called today just to find out if i can get the tracking number and was advised very blatantly that the confirmation department needs to call me in order for me to get a tracking number , this was not explained to me the first time round all that i was told is that 1. there is no stock but delivery should be 3-5 working days 2. my contract has been approved so now here is where i get annoyed you have all my personal information i was told that it would be approved and today im hearing a totally different story. I've given personal information such as my banking details and i really dont think this is right or fair towards a first time customer . Really wondering if i have made the right decision
