PORTLAND, Maine — FairPoint Communications Inc. says it’s focusing on its call centers, its billing process and the way it handles orders as it attempts to straighten out problems that have plagued the company over the past two months.

FairPoint on Wednesday made public its nine-page “stabilization plan” created at the request of the Maine Public Utilities Commission.

FairPoint says it has resolved its billing problems for the most part and is putting most of its focus on properly fulfilling orders from customers wanting to get connected or disconnected or have a change in service.

Thousands of customers have experienced e-mail, billing and customer service problems since FairPoint took total control of Verizon’s wired telephone and Internet operations in northern New England on Jan. 31.
