Scam,ring tone is international dialling

Picked up this call on my mobile, no answer. Possible predictive dialer. I have recently received an upsurge in unsolicited calls on my mobile, so this is quite possibly a predictive dialer targeting phone pick ups for follow up. Caution advised.

Said it was Greenpeace, looking for donation, had my email address, but was pushing for credit card details. Hung up.

Starting to call me every day

Picked up but no answer, then hung up. I can’t stand these time wasters!!

Hung up as soon as i picked up, area code is of central coast nsw. Seems to be a call centre like others suggested

Caller: Unknown

Scam think it is a call centre

Calls twice a month for two months, calls for two seconds then hangs up . have blocked number.

Missed call, no message

missed call no message on 19 November - assume it's another call centre
