I called back number 0432 061 912 rang once then goes to busy tone.

Missed a call from this number. Tried to call back and it was disconnected. They called again. When I answer it a woman (most likely o/s) who asked for my email address so they could send me an offer. I spell out a vulgar email address to which she is non the wiser and tells me she will be in contact via email. Sounds like a scam to me!!!!!
