No Customer Care

We have endless problems with our connection, now we are being told that it is the cable from the black box giving problems and Rapidnet wants to charge me a call out fee for a faulty product which they keep telling me to unplug and plug in when I contact them with problems. I have to contact them every single day about the drop in the internet. I do noth think that it fair to us as customers to pay for something they tell me to unplug and plug in and now is "damaged" because of them
