Solfan1 Limited was closed down by the High Court four months before her Ms Yates’s wedding, on 1 May.
Ms Yates has been told she would not get her money back because of the way she paid via direct debit.
On 29 April, she received an email from The Best Singing Waiters asking her to pay the final two direct debit payments to a completely different company, called Decameron Events Ltd.
The only contract she held with The Best Singing Waiters was with the company, Solfan1 Limited.
“I was asked to set up a change of payment. It was to a company that I hadn’t heard of before,” she said.
“They told me that my old direct debit had been cancelled.
“I had no idea what was going on. I panicked really, that if I didn’t do this, anything that I’d [already] sorted was going to disappear.
“It was all done in a rush.”
The has traced Decameron Events Ltd back to the husband of the director of Solfan1 Limited, which traded as The Best Singing Waiters.
