I have received one call per hour from these people, and they all have a thick Indian accent and are indicating they are from a solar company and "not selling anything." I've told them all I'm on the do not call list. The number seems to be an ex-US telephone number, and it is a different voice each hour (but still with a thick accent). Very intrusive and very frustrating. Have reported to FTC.
