Vodacom Wireless Fibre - Never works!

We have a contract with Vodacom Business for a wireless fibre connection. The line has been down for more than a week now. We phone Vodacom daily and we are still waiting for a technician to come to site. The fail over has also failed. Nothing works! While we wait we can not access our emails or the internet. Vodacom, how many times must we keep trying? Is this how you handle your business clients? Our SLA is 1 business day. It's currently been 6 business days! This is totally unacceptable!
