Bad service

Im disgusted by the service. On 28 Feb 2018 I called to cancel contract with Vodacom due to a different network having a better deal but the kind and helpful consultant was willing and able to better that deal and I gladly decided to upgrade and not cancel. I waited for my package and after two weeks I called to track my device and was told no upgrade was processed on my number and nothing show on their system. No one was able to hrlp, was put thru to different departments but what a waste of time. On March 11th I sent an email to complaints ********** and still no reply. I am so furious and disgusted the way I'm being treated. I'm leaving for sure but they owe me an apology or be able to trace that call and have me get that deal,\package I signed up for.
