I received 4 calls from them in the early am 12am 2:30am & 4am.hours,(Idiots I needed my SLEEP!) and also on my Cell # at 2:31 am, kind of creepy they know both my numbers) and several other days during normal hours.
Received a call from this number at half past midnight. When I answered, the recorded message said: "Sorry, that is not a valid extension." The call then ended.
