We are being pestered with phonecalls where the caller never says anything - over the past few weeks it has been happening daily, sometimes a couple of calls a day. It's always the same phone number because I do 1471. I've called BT to ask for their help, but when the tried to trace the number they drew a blank because it wasn't a BT number. They offered us the "Right to Refuse" option for a free trial, which we took up. Now that the month is up, these calls have been coming in thick and fast and always the same. After about 30 seconds of complete silence, the line goes dead. I've tried calling the number back but the line goes off instantly, so I'm assuming the number doesn't receive incoming calls.
Does anyone have any idea how I can find what's going on here? Has this happened to anyone else? We've had up to 7 of these calls in one day before - it's ridiculous and I can't understand why it keeps happening.
