Fairpoint Communications, which has been struggling to manage the New England DSL & landline networks acquired from Verizon -- suspended collection of past due DSL and landline bills last January as they sorted out management of the new networks. The company had planned to resume debt collection last week, but New Hampshire regulators are telling them to hold off until they fix some of the problems plaguing customers. Fairpoint's had particular problems with their billing systems -- in many cases overcharging users, or continuing to charge users after they terminated service with Fairpoint.
