More than 1,600 people have demanded a refund after a badly-organised Michael Buble concert saw hundreds miss the show completely. 

"Shambolic" traffic management at Saturday's show at Waddesdon Manor meant the Canadian singer performed his hits to a much smaller crowd than anticipated - because many people were stuck in long queues to trying to get into the venue. 

Some people had travelled hundreds of miles to celebrate special occasions, splashing out hundreds of pounds on tickets - but it was slammed as a "disaster". 

A petition, which currently has 1,615 signatures, is demanding organisers Senbla issue refunds to those who missed the event. 

James Robertson, who started the petition, wrote: "The surrounding A-roads were gridlocked as the venue refused to open two of their three entrances.

"This resulted in thousands of vehicles being funnelled in to a country road which created traffic chaos for the residents of Aylesbury, Waddesdon and Bicester.

"This meant emergency services had to drive toward oncoming traffic to circumnavigate the area.

"Upon arrival, individuals were supposed to have their bags, tickets and car park tickets checked however none of this took place.

"Instead, it was a free-for-all as thousands rushed to view the concert that had already started meaning the security at the event did nothing to protect its attendees.

"Disabled attendees were left stranded by an appalling bus shuttle system that prioritised moving staff from the car park to the concert over them."

Mr Robertson said those who missed the concert should be given the full cost of their tickets back - and if not, they will pursue legal action. 

He added: "Their failure to appropriately manage the event resulted in the event being ruined in a time when concerts are supposed to bring the joy back to people's lives."

Senbla said they would be writing to those affected directly. 

In a statement, they said: "Michael Bublé performed an amazing show in the grounds of the stunning Waddesdon Manor in front of thousands of delighted fans who had a wonderful evening.

"It was a fantastic show to start his incredibly exciting UK tour in some of the most beautiful sites in the UK.

"We do know that some customers were affected by issues with traffic management which led to delays in both entering and exiting the site, which we urgently addressed to ensure don’t happen again. Those that were affected we will be writing to directly."
