zero customer service - zero stars

I have been trying to reach RSAweb for over a week and no one answers the phone. I have asked to move my fibre to a new address and received an email with a link I was meant to follow to do so, however the link takes me to a broken page that does not exist. I have also tried to contact them via the chat function on the website which was also unsuccessful as I was told they are offline. No one is able to guide me or tell me how they can help - there is zero customer service. I have now received an email to say my fibre will be cancelled as RSA Web has not heard anything from me and cancellation/hardware fines will apply. How does that work? I have been trying to reach them and to resolve this but no efforts of mine have made any impact as there is zero responsiveness from RSAWeb. It seems that RSAWEB wants me to choose another supplier?
