Vox gives bad, bad, bad, bad, bad service.

Vox gives bad service. It's been 2 months and my internet that I pay is still not sorted out. I have 2 premises that Vox is the service provider of. The one that I am staying at is 478 Berg Avenue Pretoria North. I pay for 100mbps but I only get 19 mbps on WiFi. They did have a Technician and he confirm that he gets the same. Then they send metro fiber out. Metro fiber said all is good at there black box they see I get 100mbps but he tested with his phone of the wifi and only got 12mbps.Vox phone me back after 5 days. I told them what happened. It might be the rooter the lady from Vox said they will come back to me. It is been 6 days now and still no fixing. I have proof and screen shot and voice recordings. Every time they say it is been escalated. Now a contract is binding and I am paying on time every month.. So I do my part of the contract. But Vox is not giving any service. So this review is proof that I will give them until the end of this week. New better rooter If I must pay for that I will. But if this problem is not been resolved. I will break the binding contract on both premises and will find a new provider with better service. I think this is fair request.
