Being bombarded with scam messages is something that all of us have faced at some point - but one woman has found a nifty way of getting her own back.
Shaina Gimao, from the Philippines, shared a screengrab of her hilarious response on Twitter, in which she wrote: "Congratulations! You have successfully subscribed to Prayer Of The Day".
When the scammer attempted to opt out of her messages by replying 'Cancel', she went on to write: "Sorry, you have entered an invalid code. Please try again."
Other social media users were quick to applaud her response, with one writing "Well played!".
Sharing screengrabs of the amusing exchange on Twitter, Shaina commented: "How to give scammers a mini heart attack."
