Caller: A technician supposedly from Telstra

She was certainly from a call centre, very noisy in the background. Immediately informed me she was from Telstra and they were going to cut off my internet. I said, I wasn't with Telstra and as a result Telstra wouldn't call me. She said but Telstra was the motherboard or similar and they had the authority to call anyone. I said, so cut me off and hung up.
