A seven-year-old boy used his mum's credit card to buy a £7,600 miniature toy from eBay.
The youngster, from Sydney, Australia, splurged the huge amount on a rare Golden Billy Banana toy from the Coles Stikeez collectible range.
The young lad, who has autism, is a huge fan of the rare collectible range.
He had previously asked mum Donna Jacob's permission to buy the rare item - but when she refused - he used the family computer to search for the one.
And when he stumbled across one of the collectibles online, he used his mum's credit card details, which had already been saved, to make the purchase.
Donna didn't realise what had happened until she received confirmation of the purchase the next day.
She immediately contacted the seller to ask for her money back, but her pleas fell on deaf ears.
Donna claims eBay told her the incident was "friendly fraud" and she was unlikely to get her money back.
She repeatedly contact her bank, eBay and PayPal in a desperate attempt to get the money back.
Eventually, eBay agreed to refund the unfortunate mum.
In a statement, the company said: "eBay understands there are unique circumstances in this case. As a result, the buyer will receive a refund for the purchase."
Fortnite warning as kids told to perform 'inappropriate acts' by online predators
A relieved Donna is now calling for stricter protocol to be put in place to prevent kids spending large sums of money online without permission.
She told 7 News: "I think it's just ludicrous this could happen.
"It's certainly nothing we've budgeted for and nothing we can afford.
"Between PayPal and the bank, there should be at least one stopper that says 'hang on, this isn't right'... and no-one did.
"I just don't go out and spend $10,000 in one transaction, so they definitely need protocols in place to stop this happening."
