I called back number (02) 8317 1298 rang once then gets disconnected automatically.

Supposedly calling from some seminars service, offering a "free" seminar. I had already answered a mobile number they use and said No but they keep calling. They also use mobile 04800 27269

Didn’t answer. Presume spam call as they didn’t leave message

On the 10 October 2019. in the evening, this number kept calling me 3 times consecutively. 2 times using the 02 area code and the 3rd time using the 0612 area code. I did not answer or call back because it is an unknown caller to me, so, after reading the post on 4 October 2019, I am glad I did not answer it. I don't usually answer unknown numbers/callers to me anyway. Looks like a dodgy caller. Stuff 'em!
