Vox does not bother to address client queries

Unfortunately I have had to revert to social media as my emails go unanswered. I am extremely unhappy with your service provider TT Connect in the Benoni area. Their network is down at least every day or every second day. We have established that it relates to general TT Connect outages. As i have signed the service contract with Vox, i have requested that i be credited for downtime - no feedback from Vox. I also request that i cancel my contract with TT Connect as service provider and move across to Vumatel - no penalties or installation costs to be paid. I am not expecting a response or favourable outcome but at least i tried this last avenue. It is pure bad manners and bad customer service not to respond to emails that clients send to your official e-mail address.
