DeVos Place, Grand Rapids, Michigan. Katie Oquist, Accounting. Keeps calling my phone too. Just called here again and looked it up, then saw your post.
Called here again, this time after 10 PM. DeVos Place, same as above. Answered the call but I didn't say anything, muffling on other end, then they hung up without saying anything. No reason for them to be calling here. No other comments here except mine.
You could use a call blocking device or service if your phone carrier doesn't already provide one. Then you wouldn't have to keep reporting the same thing, since you seem to be the only one getting calls from this number. If you have found out who is harassing you, then you can report it Where to report phone crime and have something done to stop it.
