(INDIANA) – An Evansville company is being sued by the state for allegedly acting as a gateway into the United States for robocallers in India, the Philippines and Singapore. The company, Startel Communication LLC, was owned and operated by Wanda Hall and Abhijit Chowdhury, an Indian national.

These robocallers allegedly made over 4.8 million phone calls to Hoosiers and hundreds of millions of calls to other states across the United States. The robocallers allegedly operated a variety of scams, including IRS and Social Security Administration imposter scams, legal action or arrest scams, computer support scams, Apple support scams, and Amazon subscription scams.

The investigation started with a few consumer complaints and took over a year to complete.

The suit also includes two California companies — Piratel LLC, which routed 3.1 million of the robocalls, and VoIP Essential LLC, which routed 1.5 million of the robocalls. Both companies knew Startel was sending robocalls, and they were each paid more than $100,000 to look the other way.

Of the Hoosiers who were called, more than 780,000 of them were on the federal Do Not Call Registry and over 605,000 were on the Indiana Do Not Call list.

The lawsuit alleges the companies and individuals committed millions of violations of federal and Indiana law, with potential fines in the billions.
