Vodacom Fibre failure

I'm still waiting for someone from Vodacom's Fibre department to call me regarding the billing dispute. Dean from Vodacom's Hello Peter department called me after hours on Friday and left a voice message. He was going to notify them to contact me urgently resolve the issue but I haven't heard anything yet. I am disgusted and disappointed with Vodacom and the horrible service I have received from them. Their customers are not important to them at all!
