GALAXY S6 UPGRADE

WHAT A FAIL! How difficult can it be for a company (with the main purpose of providing cellphone contracts and services) to upgrade a contract? Apparently very difficult. My contract was supposed to be UPGRADED, as clearly instructed to the online sales department (via a call), but I was notified today that they created a NEW CONTRACT. Also, included in the box, that I had to FETCH from the courier myself as the sales person got the address wrong, is the incorrect size SIM card. Well done Vodacom, another great service received from you!
