Hertfordshire, UK - She got seven numbers right and hit the jackpot – at least in theory. Then the young English woman found out that an unfortunate mishap caused her to lose a fortune.

Rachel Kennedy (19) and her boyfriend Liam McCrohan (21) could now be multi-millionaires, as the couple from the county of Hertfordshire in the UK hit seven numbers in the lottery on Friday.

For weeks, the two had been betting on the numbers 6, 12, 22, 29, and 33, as well as the additional numbers 6 and 11. With exactly this combination, they could theoretically have won the Euromillions Jackpot of 182 million British pounds, the equivalent of about $254 million.

But even though they had the right numbers, they didn't get a penny – for the simple reason that they hadn't paid for their winning ticket correctly.

As the Sun reports, Rachel used an app that automatically bought a ticket for her with her seven numbers over and over again. That's why her mobile phone initially notified the 19-year-old on Friday that she had won.

But when she phoned the lottery company to find out, she was in for a shock: the app had run out of credit and was unable to buy a ticket on the 19-year-old's lucky day!

"I was on top of the world when I thought I had won but when I found out I hadn’t, Liam was actually more upset than I was," Rachel said. Her boyfriend also shared the mishap on Twitter.

His tweet with the (un)lucky numbers has already received more than 35,000 likes within one day, but what's a few thousand Twitter likes when you're missing out on £182 million?

Liam said that his girlfriend had remained relatively calm, but he had been devastated: "I was already picturing our dream house and the dream car."

Nevertheless, the two apparently still want to play the lottery, but "absolutely not" with the numbers 6,12, 22, 29, 33, and the additional numbers 6 and 11.
