Vox Terrible Customer Service Support

I have been without consistent WiFi access in my house for the past 3 months. I called for over a month asking for a technician to come out and sort out the poor coverage in my house but to no avail. I finally wrote a heated email to their customer support centre and they finally sent the technician. However, when he left after claiming there is no issues with WiFi transmission in my house, the situation went from bad to worse. I cannot stream anything in my house even in my room where the roofer sits. It buffers the whole time and times out. None of my devices in the house are picking up signal from the rooter and the extender, it’s a complete disaster! And when I call, they tell me a service technician will get back to me. I am still waiting.
