Over 3 weeks of you delivery after upgrade-now Vodacom has flagged me on their system because I have been calling everyday

Over 3 weeks for an upgrade, now Vodacom has flagged the numbers that I have been calling them from, on their system so that I cannot speak to the upgrades department....!!! This is all because I just wanted them to sort the mess that they did on their side that has resulted in me not getting my phone and sim (deactivated by the way) delivered to me, after doing an upgrade on 14 Nov 2017. I have been taken from pillar to post, from one *********** consultant to another, from one *********** team leader to another, all in vain.

CAN SOMEONE WHO KNOWS WHAT THEY ARE DOING SORT THIS MES OUT.

I have even taken to writing an email to Vodacom CEO, and all that I get is an automated email response from **********

Can I then ask that my contract with Vodacom be cancelled so that I can get on with my life......!
