Poor customer service

My fibre network is down since Friday and some other houses on my street have been without network since Wednesday I've been contacting the call centre and only get AI responses when I finally managed to speak with a human they booked a tech to come out to my place he came on Saturday took a photo and says that the issue is not in our building it's a street fault then on Monday the same technician comes back to take another photo of which he did do on Saturday which was a waste of my time because he never resolve anything then I'm trying to get a response via email by the complaints department is another hassle nobody responds I've sent 3 emails and sent messages on Facebook messenger and I get an Ai response and it's really disappointing to receive such pathetic customer service from such a large internet service provider because the call centre agent's, the complaints department and the support department don't have any courtesy of calling the customer back to find a resolution to the problem.
