Terrible service

Extremely dissatisfied with Vodacom. I did an upgrade and app**** for a new contract on the same. A week later the new contract arrived but not the upgrade. Its now been 2 weeks and all I was getting told was call next week there isn't stock. Today I get told the upgrade was cancelled. By who I asked and the lady couldn't even answer me. Not even a call to say we don't have stock we have to cancel. Extremely dissappointed. Spent 4 weeks calling and waiting for a up grade that's cancelled by them.
