Vodacom Bad service

I recently pre ordered the S9+ from Vodacom... Everything went smoothly until RAM phone to deliver the package... unfortunately I damaged my ID so couldn't submit it.. They went away to confirm if it is possible to work with my Drivers. I heard nothing since.. Following this I went to the Vodacom store to do the upgrade in person. I have a few serious complaints after this Firstly.. on the online the upgrade fee is added to the account.. in store.. not possible. Then I was told that I have 2 month left on my device payment ... on a device that was pre ordered Feb 2016. Please explain that?? Something that wasn't mention on the online order! I've got 2 month left on my contact this is from the pervious upgrade? Then what caused the issue is the ID needed for RAM to deliver and that a Drivers won't do.. But in the store drivers is fine!!!!??? Now since this delivery issue hasn't happened I lose my benefits of the pre-order.. so what's the point!!!
