Indian caller said she was from Telstra and they had noticed that my router was showing varying speed for internet and was slowing down, and they will correct it. I said it is fine and I have no problem, and she said "no, we are recording different speeds and will correct it for you". When I said, what are you planning to do, she said we are going to scam you.........and hung up!!!!!!! Another daily scam call. So tired of them.
