I have an issue with my neighbour who thinks it is fine to us his mobile phone late at night 11:30pm early morning 1am, 3am and even 4am. I have to get up at 5am every morning for work and I have told him to stop it. His answer was you are at your house and I am at mine. When I do wake up for work he is fast asleep snoring having a good sleep and will not be getting out of bed till 12pm. I have spoken with the council and they have said that it is a nuisance but not a noise nuisance so we cannot do anything. I was thing of some sort of mobile phone signal blocker which I can switch on at 9pm and then switch off just before I set off for work. Is there something on the market and where can I get this?
