Upgrade delay

So I contacted vodacom to do an early upgrade, I was advised that the conformations dept will contact me. They did call me but hung up and I'm still waiting to be contacted, this isnt the first time I've experienced this issue, the Huawei deal I upgraded to has a promotional gift which needs to be claimed after the device is received, if I miss this due to this I will be quite upset, it's also so concerning that I cannot be transferred or given a number for the confirmations dept. Also no cofirmation SMS or email was received confirming my order
