our business received multiple calls from this number he was an Indian (will not say gentleman as he definitely is not a gentleman) stating that he was calling re Telstra line usage, we advised that we did not want to discuss out phones with him and we hung up, he continued to call saying that he would keep calling until we listened to him, I requested to speak to his supervisor and he tried to change his voice so I just ended up putting the phone on the desk until he hung up. We are a very busy business and rely on our phones for our customers to call in. To have people like this calling our business an not taking no for answer is tying our lines up. Very very annoying. It took our CEO to use very strong words to end the continual calling.
