Received a call on my landline and I answered the call as it Ausytralian phone number, the caller said he is from Telstra and this is regarding my internet is having problem.
I told him that, I am not Telstra customer and my internet is fine.
He said there is lot of noise, I replied there was no noise. I shouted and told him to stop this cheating people, he said mind your language, I said shutup and cut the line.

The callers voice was Indian.

Caller: "Telstra Technical Department"

Answered call to hear "Hello, I'm from Telstra Technical Department". We said "This will be interesting" and caller hung up.

I said "hello" about five times and then he said 'sorry' and hung up. Blocked the number.

ringing every day, never leave message

Number listed to 'A. Fogwell' according to this site but I don't have the foggiest notion who that could be. I did not answer and blocked the number.
