They completely fucked us over for the first 2 months or so. Our internet would work for about 5 minutes, then go off for 5. If you reset the modem it'd work for 10 minutes or so, then start the cycle again. My Dad complained honestly about 10 times on the phone, and every time for the first 8 they'd say, hmm, no problems on our end, nothing we can do. So my Dad buys a new modem, still doesn't work properly. Complains again, so they send an engineer out. As per, it works fine while somebody who can fix it is in the house, then goes toshit again as soon as he leaves. Then my Dad got another engineer out, who replaced the modem with a more recent model and gets it done for free because of all the shite it had taken to get that far, and its worked fine ever since.
Stick to BT or someone
