I called back number (02) 2566 4534 rang 2 times then goes to busy tone.

They called me saying my line would be disconnected if i hung up saying they were from telstra. Hung up anyway.

Had call from this number yesterday - no message left .

Called at 6.07pm. Woman - poor English - calling about my internet connection. What internet connection? Silence then terminated 1min 38 secs

Voice said something - English so poor and so gabbled, I couldn't make out out words, except it might have concluded with, "How are you today?" I asked for clear, so English, the phone was held with no comment and eventually, the caller hung up.

The caller claimed to be from Bigpond and said there was a problem with my internet connection.

Answered a call. Silence, then automated voice said, "Goodbye!"
