A woman who ordered a fish-themed cake for her angler brother's 30th was furious when it arrived covered in hairs.
Graham Faulkner's birthday was "ruined" after an online seller produced "something that looks like it was made by a child".
His sister Sam Faulkner paid £35 the woman on Facebook after being impressed with photos of her cakes on Pinterest.
The "Emma Beth Mh" account had used pictures from CakerStreet.com company which have now been deleted, BerkshireLive reports.
Sam's mum, Sue Faulkner, of Reading, Berks, shared pictures of the "laughably bad" cake alongside what was advertised on a community Facebook group.
She wrote on the Earley Residents Discussion Board: "It ruined my son's 30th birthday especially in lockdown.
"We are not even touching it as it has cat or dog hairs on it.
"We did laugh, so funny, but upsetting for my daughter who was conned!
"Paid £35.00, she did offer my daughter a £10.00 refund lol."
Mrs Faulkner told BerkshireLive: "My daughter was distraught at when she opened the box. It was nothing like the picture.
"She'd paid half the money for the cake to this woman and what came back looked like it was made by a child. Honestly, it was laughably bad.
"The name Graham didn't even have a capital letter, it was that bad.
"I was very cross, so I said 'I'm putting it on Facebook'. Once I did that, it became clear there were other people who had encountered her as well.
"I tried to contact her and she blocked me straight away and deleted the page."
BerkshireLive also tried to contact "Emma Beth Mh" through Facebook, and the page was immediately taken down.
Mrs Faulkner said: "I'm going to Trading Standards as she's clearly not a proper cake maker. We're now able to see the funny side of it afterwards, but at the time we were very upset.
"Even though we had a laugh about it, I still want to warn people this fake cake maker is out there producing these monstrosities and charging people for these terrible attempts at cakes."
Sue said the woman was initially reluctant to give her daughter her money back, but £15 has now been returned which is "about as good as we'll get".
It is thought the cake maker lives in Reading and a spokesperson for Reading Borough Council said the authority has received complaints and was carrying out an investigation.
The council added its Environmental Health team was also involved.
