Ray Hadley is urging his listeners to keep their eyes peeled for advertising from the dodgy Plumbing Detectives.

Ray has exposed the company in the past for massively overcharging and ripping off their customers.

Now, a listener has warned him they’re back at it again, but are leaving their name off the fridge magnets they’ve been delivering around Australia.

Ray has called the number and confirmed they are the infamous Plumbing Detectives operating under a new name.

He’s warning all his listeners to throw the magnets away if they receive them in their letterboxes.

“Put them in the bin because no matter what happens you’ll end up out of pocket.

“They are the Viagogo of plumbing and electrical.”
