Caller: Someone said who is from Telstra

An Indian accent lady called from this number and said she is calling from Telstra. She said she received information show that my internet line has a issue. I told her I'm not with Telstra. She said Telstra is providing internet cable to all Australia home. I told her my internet line has no issue, she said you are not technician and please turn on your computer so that she can tell me what's wrong with my internet line. I said I'm sure I got no problem with my internet line. She still asked me to open my computer. I told her I'm going to report her because I don't think she is from Telstra. She hang up.
