Caller: Optus

I imagine it was Optus, though no voicemail was left. 2 calls from this number in the same day. I just activated a new Optus SIM and nobody else knows my number. So who else can it be, apart from Optus themselves? Since I activated the Optus SIM, they keep spam-texting me with offers: and like anything else in this world, I shouldn't have to bl**dy well unsubscribe from something that I never bl**dy well subscribed to in the first place! It's only early days, but I already regard Optus as pests. Then again, who can we trust in this society?

I called back the number (02) 8049 0849 and reached vm that said I reached Optus

Just greeted and when i replied said a sorry and hag up
