No internet

I have been experiencing internet issues with surf4life since I moved into a new property last week. I have logged a ticket and was informed that there is nothing wrong with my internet on their side and the ticket was closed. I rep**** by opening a new ticket for the same issue and was informed that my connection has been reset and is working fine on their side, but on my side I am having the same issue still whereby the internet connects for few seconds and goes off again. Today it's worse whereby on all my devices it shows no internet and after troubleshooting it shows connected without internet. There is no orange light on the router only 1 white light. The router doesn't go off when you switch the plug of it only goes off when you unplug the power cable. I am not getting a response from the service provider though i have provided screenshots and even asked could it be that there is a cellphone tower around the corner from where I stay. It is frustrating because I use the Fibre for work purposes and I make sure to pay the account on the day that it expires, is this what i am paying for, me having to spend double to buy data on my phone just to be able to work after I have already made reservations to pay for my Fibre inorder for me not to struggle? This is the worst service I am getting from this service provider as I have been using them for a while now, not even a response on the whatsapp that I send them, not even a technician coming out to check what is wrong.
