Worst customer service I have ever experienced!

Worst customer service I have ever experienced. For almost a month now I have been billed pro-rata and been debited a full amount for a 100mbps line and now I am barely getting speeds of a 20mbps line. I have contacted these people so many times that I have lost count. I am desperately wanting to cancel but don't have any other providers in my area yet. How are we living in 2024 with such poor wifi infrastructure??

What adds to it is the fact that I work in the evenings and that's when my speeds are at it's lowest, when nothing else is on the wifi except my speed test I am getting speeds of sometimes 2mbps and maybe 20mbps if I'm lucky. I don't know what else to do except leave reviews.. I am disgusted with their customer service.
