Caller had called my mums mobile trying to sell electricity. She persistantly told him she was not interested. Caller had heard in the background a swear word which was not directed at him. When she hung up, he called back 3 times threatening to report her and saying that calls were recorded. She persistently told him to leave her alone. Caller then wanted to speak to my father who is 76 years old as he assumed my dad had sworn at him. my mum told him to stop harassing her and then he told her he was going to F#@ck her in the mouth and hung up. I need to know what call centre this was so i can report the scum bag who is harassing the elderly.
