i have been with plusnet for a fair few months now, and have missed payment on a number of occaisions. te worst the situation ever got was where my connection was down. understanable right. one call to plusnet and i was back up within minutes!
also, i have about 99% uptime i never seem to lose my connection and have been online currently for 72hours or near about. i find plusnet very helpfull. compliant and a generally good ISP.
