Poor service by Vodacom

I have had a horrible experience with Vodacom in the past two days while trying to give them some business by upgrading my existing line. I ended up calling different branches (upgrades, cancellations, migration, customer care etc.) and engaging with different consultants some of whom were clueless and some made wrong referrals! Ultimately there was no solution and sadly I am forced to cancel my contract and take my business elsewhere.
