I tried to call back the number (08) 7905 7177 but the person who picked up the phone disconnected the call

Caller: Emily

They called my son who has an intellectual disability and were about to obtain his credit card details to commence a online trading account. Luckily I was able to intervene.
My son stated several times that he requires his parents guidance to make financial decisions, however they continued to state “it’s ok your clever enough to make decisions”.

I dialed *10# and then 1(to call back) and it said it could not be connected
