One of Frontier Communication’s largest legacy service areas is suffering from some of the same bad service reported by rural communities in states like California, Minnesota, and Florida.

News10NBC reports that some customers in Rochester, N.Y. have spent “weeks without reliable telephone service and very few answers.”

Frontier landline customer Andy Melnyk says the problems with his phone service began six weeks ago. The line frequently goes dead with no dial tone, and customers calling the Rochester family get nothing but a busy signal.

“I thought okay, they fixed it, let it go and then it happened again,” Melnyk reports. Despite the service problems, Frontier has not offered any bill credits, or a satisfactory explanation for the problem.

“[It’s] just like a black hole, you can’t find anything out,” Melnyk’s wife Kay told the station. “They’re not being very transparent about what the problem is, [and] what they’re doing to solve it.”

The Melnyk family is not alone. Other Frontier customers in the neighborhood are dealing with the same issue.

It took News10NBC to get involved to get a statement from Frontier, claiming the problem is a wet copper cable.

“Frontier technicians are working to repair a large-diameter copper cable damaged when recent rainstorms flooded an underground vault,” Frontier said in a statement. “Services were restored for affected customers by March 7, however, the permanent repair process needed to splice new cable is complex and takes time. We expect to finish the work this weekend. We thank our customers and the communities we serve for their patience as Frontier crews work safely and diligently to maintain our network and keep communities connected.”

Maintaining deteriorating copper wire infrastructure that other phone companies discarded years ago in favor of fiber optics can be complex and time-consuming. But other companies have found upgrading to fiber has given their networks more reliability and happier customers. But Frontier has shown no signs of launching fiber upgrades for customers in their legacy copper wire service areas.

Meanwhile, when asked if Frontier customers will receive bill credits for the problems, a Frontier spokesperson told the station they will consider that on a “case by case basis.”
