Terrible Service

I have been a loyal Vodacom contract subscriber for some time, (I currently have two contracts with them) I have been paying exorbitant bills for some months now due to out of bundle data, even though I have had a voluntary limit enabled on my account. I wanted to upgrade however my account needed to be settled after a large amount was due. I went to the Fourways Mall branch where I was told I should go to Vodaworld for the payment to take effect immediately. At Vodaworld I waited in customer services queue for some time to pay. I was told that I would be able to upgrade as soon as payment was made on my account, which I did. I then went to Smartcom to upgrade and they advised that my account was still blocked and they could not upgrade. I was then advised that the staff who could unblock my account had gone home already! 14:30 on a Saturday afternoon. I was back at Vodaworld on Monday, and again on Tuesday only to be told I cannot upgrade my contract. I will be cancelling both of my contracts and moving to another provider.
