HOME CONNECT/VUMATEL - NO SERVICE / NO CONNECTIVITY / NO RESOLUTION

I wish there was a "ZERO" star rating that I could use! I have previously had fairly decent service from the company however, the last few days have been nothing short of painful! No internet access (day 3 now!), no communication, no feedback, no resolution, no proper explanation. I have called REPEATEDLY, sent emails to NO AVAIL. Spoke to a manager at lunchtime yesterday, he promised to call back in 10 minutes, now 24 hours later still no call. Promised a call from another manager this morning, still nothing. APPALLED BY THE LACK OF SERVICE. I cannot operate for 3 days with no connectivity, it is UNACCEPTABLE! Our whole complex (171 units) is affected and I believe the 2x neighboring complexes are in the same boat.
