Devastating service.

I don't even know where to start I have been without my WiFi for almost 3 weeks, I have called numerous times, all I can ever get is that there is nothing wrong with my device or the network. My daughter is writing exams, my son watches his programs that needs internet. I have buying expensive data which should be reimbursed. I asked my partner to take the device to the local outlet as I was advised and they said I should be there. How am I expected to leave my workplace and drive 150km... For reference purposes my cellphone no.is ***
