ISP with the worst customer service experience to date

This is the second time I've used Vox as an ISP. The first time was a poor experience and I thought I'd give them another chance. Nothing much has changed. Ordered fibre over a week ago, RICA process was almost instant but no progress since. I ordered for a family member since and their RICA process held them up for two days, then the next day the fire was scheduled and installed the following day. Yet for me, nothing.

Emailed them 5 days ago. No response. Have called in about about 10-15 times, most of the times and either get put on hold, disconnected, I sometimes get to speak to someone who puts me through to someone else which just goes to voice mail or if I choose the option to have someone call me back, no one ever does. Just a moment ago I was put through to the projects team, I was no 28 in the queue and after half hour of waiting, I'm down to no. 26. Your service cannot be this bad. So far I've wasted about 3 hours just trying to get hold of someone who can assist me, but without success. I might as well just give up with them. Even Telkom has been a better experience.
