Called Back (03) 8899 9042 and it was a company saying optus bussiness phones , but asked if I was with Vodafone or Telstra , dont touch it I woudl say

Rang me twice didn't answer either. They left a silent message on 2nd call. Avoid.

Bad line, alleges he's from Vodafone and ask to speak to the one who handles mobiles. I suggest you don't answer or hang up.

voda phone sc

Says they are with Vodafone but I am already with Vodafone so sounds dodgy. They wanted to update my plans but I had literally updated my plans with Vodafone a week ago.

Said number not available or invalid.

I called back number (03) 8899 9042 reached voice mail but did not say from what company.
