"Development Issues"

I'm up to my ears in frustration. A week ago my Fibre was disconnected on time with Vodacom as I was moving over to Cool Ideas. I accepted the supposed downtime connections of 3 days. It's been now 7 days and my constant phoning us getting no where. Apparently Vumatel is not allowing new orders to get into the open lines. They are having " development issues". I cannot go to another isp as I will experience similar problem due to the fact that Vumatel installed my Fibre lines. What are we to Do? My tv uses fibre , our phones, our business. We are losing time and money. It's extremely frustrating and sad. Will someone from management ease sort the problem out.
