Vodacom Fibre unreliable

Vodacom Fibre has been offline for 2 days at my office park. I have already lost a lot of money because of this. I phoned the call centre, refusing to end the call untill they will give me an estimate of when it will be back online. The one "superviser" even cut the call. I spoke to numerous call centre agents that were going to phone me back (never happened). I ended up phoning again and eventially spoke to Nathan that said that it will be back by the end of the day. Even though he gave me an estimate it is still my company's lost. One of the call centre agents even told me that I should buy another plan from Vodacom for incase the fibre goes down. Why do I need to pay for backup for when Vodacom cannot provide me with the service I am already paying for? This is ridiculous. Will they pay back the R10,000-00 I already lost? How do I cancel my contract with Vodacom? This is a risk to my company I cannot afford.
