CONCORD, N.H. (AP) — FairPoint Communications wants to start collecting on customers’ past due phone and Internet bills. New Hampshire officials want FairPoint to resolve its own billing problems first.

FairPoint, which bought the landline network in New Hampshire, Maine and Vermont and has been dealing with numerous customer service complaints, suspended its collection practices after taking over in January.

FairPoint recently told the Public Service Commission it planned to reinstate the process to preserve badly needed cash reserves, the Concord Monitor reported.

The commission said it wants to review the plan. Commissioner Clifton Below said he’s concerned about how customers with incorrect bills would be affected by a collection procedure, but FairPoint executive Jeffrey Allen said those cases wouldn’t be affected.
