Caller: Claims to be Telstra regarding internet disconnection

Threatened to disconnect my Telstra internet connection and I asked him to go right ahead because the internet speed from Telstra to my house is so superslow that they can keep all the bits and bytes. The agent asked if I am sure about that request because it can not re-established. My response was this slow internet connection is no longer required and he then hung up bare in mind no Telstra connection here in the first place.
