The sick con sees the scammers call up their victims, making the claim that they haven't paid for services or products.
After a discussion, the scammers then hang up, hoping to prompt their victims to call back.
But if they do, they discover it's a costly premium rate number, Derby Telegraph reports.
The scam has already been carried out on one woman, who says she received a call from an 070 number claiming that she hadn't paid for a taxi.
She said: "Then my mother-in-law got one from someone claiming she had ordered a pizza – which she would never do because she has a dough allergy.
"Thankfully we had the sense to hang up immediately. After a lot of investigating we found out that these are premium rate numbers and the idea is you phone back to complain and get stitched up by paying for the call."
A recent report by Action Fraud showed that thousands of fraud reports that were received featured 070 numbers, which transpire to be premium rate numbers.
Premium rate numbers are used for telephone calls during which certain services are provided and prices are higher than normal.
Anyone who is contacted by an 070 number is advised to be 'wary', as this could be a scam, and not to call the number back.
It is also advised to report the call to Action Fraud on 0300 123 2040 or by visiting www.actionfraud.police.uk.
