Extreme frustration and poor service

I have had extremely poor service with Vox Telecom. We have business wifi with Vox telecom and had no connectivity for over one week. After many calls and back and forth over email this was only fixed more than 8 days later. We had to buy additional equipment in the meantime as our business can't function without wifi. Since then I have been passed between different stakeholders at Vox with no conclusion whatsoever. I am still waiting for resolution of my cancel request and have no clarity over whether I will be billed again. Vox took no responsibility for the 8 days of wifi downtime and have refused to apply credit to our wifi bill. This has been an extremely frustrating process which has not been resolved.
