Angry on how vodacom treats customers as myself

I'm very disgusted with vodacom, I'm not advised or even contacted regarding the contract that I did online with vodacom upgrade department, and when I called the customers upgrade department for three days regarding the upgrade it was wrong on what i suggested and wanted. I'm have been with vodacom since 2006 and yet i am treated badly and not at all dealt with respect. I'm not upgrading anymore, and I've cancelled the two upgrades with the cancellation department, if I do upgrade, I will upgrade on on the lowest amount, to show vodacom I do not care. I am over been treated unfairly, listen to all the recordings and you will know on how angry I am.
