Well we chose plusnet because they were the cheapest for the speed and amount we wanted in our area.
They then quoted 2 weeks for the internet to be installed. After 3 weeks internet was installed in the wrong flat (like how does that happen). Then quoted 4 days to change to right flat (took 9 days). Then called up again and apparently the copper wiring was broken quoted 3 days to fix. 8 days later ''Support Team will investigate your issue as soon as possible.'' So they haven't even sent anyone to fix it.
They quote best customer service and to be honest yes they are nice people but as for the service, the days quoted, and internet still not here. I wouldn't bother going through this hassle just to save a few quid.
