Britain’s worst cold callers: Firm behind 100 million nuisance calls given record £400,000 fine

There’s nothing more annoying than picking up your phone to hear a robot voice babbling about an ‘accident that wasn’t your fault’.

But if you’re being bothered by persistent cold calls, a clever new trick might scare off the companies for good, according to Digital Trends.

It’s worth noting that you do have rights, and if you’re being bothered by a lot of cold callers, you can take legal steps to get rid of them.

If you’re being bothered by a lot of cold calls, a great first step is to register your number with the Telephone Preference Service (TPS) – which makes it a legal requirement for cold callers not to call after 28 days.

But if you’re still under attack, there might be a more cunning way.

Tech expert David Cogen says on Digital Trends that you can stop persistent cold callers by playing them a recording of a ‘this number is not in service’ message.


Cogen says, ‘Believe it or not, you can fool telemarketers by playing a message that says your number is not in service. You’ll merely need a recording of one of those disconnected phone messages, which you can then play whenever a telemarketer calls.

‘First, buy a recorder – preferably one you can plug into a headphone jack, so as to record the “not in service” message with better clarity. Afterward, find a “not in service” message, which you can easily do online, and record said message.

‘When a telemarketer calls you, answer (preferably in a quiet place), but don’t say anything. Play the recording, and the telemarketer on the other end, be they person or robocaller, should determine that your phone number is not in service, and remove it from their call list.’
