I called back number (07) 4410 3325 spoke to a guy who said company name is Wyndham vacation resorts.

Caller said they were a vacation company

they have rung me 3 times and when I answer they say nothing, must be a scam to get you to ring back

I don't know anyone in Townsville so didn't answer.....came here to find out its a telemarketer :)

they have called me three times, each time I have picked up so far, I answer, but they just hang up on me.

they keep calling but hang up when I answer

Hello, Wyndham vacation resort.

Say they're from Wyndam vacation resorts with good news for me, asked for me specifically. Took 3 times of me saying not interested for him to get the hint

This number (07) 4410 3325 has been calling and when i answer no one responds so have blocked them
