Bad customer service

Vox Telecom probably has the worst customer service, I've ever experienced. Today is day 8 since I've received the router via courier, haven't use the Fibre connection at all because it won't connect to the internet. Yet they send me an pro-rata invoice form since the router was delivered. I've been on call with them the whole week, trying to have this sorted but nothing. Mind you.. My airtime, my time. I canceled my previous internet provider hoping to receive better service at Vox, my biggest mistake. We are a family of 4 in my household all relying on internet.. Guess how much prepaid data we had to purchase for this week alone. I don't want to name and shame people from Vox who answered the phone trying to assist me but I must say their customer service is terrible! To add to this I've emailed them including the accounts department, again no response what so ever. Let's see what happens in my bank account on the 25th.... Vox will there be any deductions as per your invoivce???? Come fetch your stuff at my house.. Mxm
