Same happened with me. In fact, they call every morning at 8:45 a.m. and then again every afternoon.
I did a *69 and they said they were a Contour Adjustable Bed company. But when I did a reverse lookup, it says that number is owned by Broadwing Communications, LLC, in Queens, NY.
Four to five times per day, early morning ot close to midnight ( been ongoing for three weeks already) . No message left..... all unwanted and harassing calls. Got to stop that !!!
