I have no idea who is calling... but they woke me up this morning and did not even leave a message, but they were damn lucky I did not answer the phone. Calling me at 0845 in the morning on my only day I can sleep in.
Called at 9:47am and immediately hung up. Phone # must be a predictive dialer collating information on what phone numbers are active. I tried to redial it and it wouldn't ring through. Not sure who it was.
