Same here - they call, I answer, they hang up. If I knew how to work my phone better, I'd put them on a blocked list

also got a call today 12:19 pm AEDST and hang-up when i answered.

Yes it is the Cellarmasters call back number if you do not wish to speak with them just ask them kindly to remove your name and number from their call list or database and they will do so...

Rings mobile & home phone, hangs up when I answer.

Me too. I had the some call, they call about 3 time a day. When i pickde up it did not say anything then after 15 seconds it just hangs up.

4 calls in last two days, caller hangs up when I answer. PEST!!

Same with me.
I'm getting an air horn and will blast them.

I had the same issue? Why they called but did not say anything?? I dont understand.

Same problem - hangs up as soon as I answer

5 calls to my mobile in the last two days, when I answer the caller hangs up.

3 phone calls within 5 minutes , I answered but caller hung up.
