I received a call from this number which only has 9 digits instead of 10. It seems to be one in question when trying to get some information from it using a research engine page.
Been receiving calls from 23-456-7891 so today answered the phone. There was a delay & then a woman with an accent came on which was hard to understand. Asked her more than once where she was calling from & never gave an answer. Just wanted to talk with the person in charge of the computers. I told her not interested & take me off the list.
