My dad receives loads of cold calls on the telephone from scum trying to con him or take advantage of him. He is 70 and has parkinsons disease. How can i stop these idiots ?. I try to answer the phone for him and tell them we aren't interested. I have signed us up to the tps but its useless. I have complained to trading standards and my mp but they are useless too. I've found an e petition where you can sign to stop cold calls. Its at www.nuisancecalls.net
