DENVER — The legal troubles for CenturyLink appear to be growing after lawyers with Geragos and Geragos Law Firm filed a class-action lawsuit against the company Monday.

The attorneys have teamed up with lawyers in Colorado from the Shuman Law Firm and the Gardy and Notis Law Firm.

The lawsuit will be similar to what was filed in Arizona last week, alleging employees of the company fraudulently added services to customer accounts to meet sales goals — costing customers as much as $12 billion nationwide.

The first lawsuit is being brought by a fired employee claiming to be a whistleblower.

“Colorado seems to be the epicenter of CenturyLink’s corruption,” said Ben Meiselas, an attorney on the lawsuit.

Meiselas said they are filing in federal court in each state because each state has different consumer protections.

“The amount of responses from Colorado have been overwhelming,” Meiselas said.

Anyone who believes they were impacted by CenturyLink employees are asked to email Geragos@Geragos.com or call the Problem Solvers tip line. 

CenturyLink previously denied some of the accusations in a statement.

“Unfortunately, these types of opportunistic follow-on claims are not unexpected. The fact that a law firm is trying to leverage a wrongful termination suit into a putative class action lawsuit, does not change our original position. Our employees know that if they have any concerns about ethics or compliance issues, we have an Integrity Line in place, 24 hours a day, seven days a week. Our former employee did not make a report to the Integrity Line and our leadership team was not aware of the alleged matter until the lawsuit was filed. The allegations made by our former employee are completely inconsistent with our company policies, culture and Unifying Principles, which include honesty and integrity. We take these allegations seriously and are diligently investigating this matter.”
