The ticketing system for the 2012 London Olympic Games has been criticised as being confusing by consumer body Which?
The attack comes a week before applications for buying tickets to the games closes with a deadline of one minute to midnight on April 26.
Matt Bath from Which? told Sky News: “There is a lot of confusion around the payment of tickets.
“A lot of consumers seem to be stuck still in the starting blocks when it comes to understanding what they are going to get and how they are going to pay for it.”
He described the system as too complicated.
“There seem to be an awful lot of hurdles in the way of buying these tickets,” he said.
“People have to have the money in their bank accounts, because the money is taken from their account often many weeks before they even know what tickets they are going to win.
“So not only is it a lottery but it’s one you’re going to have to pay for upfront before you even know if you’ve bought any tickets.”
Games organising committee chairman Lord Coe said he was happy with how sales of the 6.6 million tickets were going.
“It’s been strong, it’s healthy, it’s across all sports and it’s also, importantly, across all parts of the country,” said Lord Coe.
