Use a compressed air horn directed at the mouth piece of you phone. Works well for all annoying calls. Can be purchased in the sporting goods sections of most major stores. CAUTION> Very, very loud.
My wife is getting this call as well. About 20 times in the last hour. Very annoying. We tried calling it back and got the "Customer Service" recording that others have said they have received. This is completely frustrating!!!
My boyfriend has been receiving the calls from the same number about every 5 mins as well. I don't know why they keep calling, but it's pissing him off just as much as it's pissing me off. But when i call it with my cell, it says that the number cant be dailed. And i tried it 3 times..
