I was sent a bill addressed to the previous owner of my house. He moved nearly 4 years ago. The bill is in his name but my address and is for oil supplied to a completely different address. Numerous phone calls later and NOW certas keep phoning. Asking me to scan and forward the bill. They already know what the bill says because they sent it! Here's a thought....why not send the bill to the address which was supplied the oil instead of harassing me. I'm just the hapless subsequent owner of the house whose previous owner still has my address listed as his with certas. I'm expecting I'll get a poor credit rating now as my address will be associated with the previous owner avoiding payment ...even though the oil was supplied to his new address. How hard can it be to use some nous and BILL THAT ADDRESS.
