Poor and pathetic service resulting in cancelation of contracts.

Due to your poor service and that no one is getting back to me regarding my upgrade that I have done via online 2 weeks ago. This has also resulted in me paying the old contract fees for this month, supposed to the new lower contract fees. I have now canceled the first of the contracts that I wanted to upgrade.I will also start canceling and porting the rest of my contracts during this month if Vodacom can not assist me urgently with in the next 24 hours.
