They contacted me via Sittercity.com and I responded, and they have text messaged me. They were terminated from Sittercity last night or this morning, after already contacting me. I'm going to have to change my number now

ty for putting the note on here I just received message from them on sitter city and thought area code was strange so googled. so again ty :)

They contacted me via text and said they found my name on gonannies. Gonannies e-mailed me last week saying this family had been terminated.

I got a call today that sounded like a recording of a woman who seemed to be having trouble with her phone and asking if I could hear her.  It was strange

I got the exact same message. A women kept saying, "hello, hello, can you hear me, hello, hello, I think I have to fix my phone, hello". Then she hung up and within a few seconds that same number called me back and then they hung up without leaving a message this time.
Very strange indeed.
