I had just purchased a new cell from T-Mobile and - in the span of time before my old number ported - I got 3 calls from 823-2020 and 823-2021.  I answered the third call and it was a phone survey from T-Mobile.  Apparently, this number and others in sequence (-2020,-2021, etc.) belongs to Western WATS Data Collection (westernwats.com) in Ogden UT.  Their direct line is 801-373-7735 for the in-house no call list.

We get several calls a day.  No messages left.  They are a nuisance.

They identified themselves on my answering machine as American Viewpoint and wanted to speak to a registered voter in the house.

Calls come in every day from this number.  I am sick of it.

Got 4 calls today ,none of which I answered. No message recorded. They are a nuisance and violate the do not call list.
