Disgusting service

It's been a month since I've paid my arrears on my Vodacom account. I've been sent from pillar to post . They have not sent the payment file to the provider yet they said they did, provider checked specifically for my one. They don't respond to emails, got the provider involved to have them send to the person assisting me but still nothing. I wanted to pay directly to Vodacom and they even convinced me that it would be faster through them. Utterly disappointed.
