First Minister John Swinney has refused to take part in a BBC Radio phone-in with voters, the only Scottish political leader who did not participate.
With just one week left in the General Election campaign, Swinney rejected the chance to speak directly with Scottish voters.
The Scottish Conservatives said the SNP were "running scared" of voters and treating people with contempt.
This morning, BBC Radio Scotland said they were told no-one from the SNP was available.
Scottish Conservative chairman, Craig Hoy, said: "Every time John Swinney interacts with the public, the SNP loses another vote.
"In numerous debates and interviews throughout this campaign, he refused to answer people's genuine questions and arrogantly dismissed their concerns.
"Now it's clear John Swinney has been scarred by the rejection of voters and he's running scared of speaking directly to people in Scotland.
"But on July 4th, whether John Swinney likes it or not, voters will have the opportunity to cast their verdict on the SNP by voting Scottish Conservative in the many key seats where it's a straight fight between us and the nationalists.
"A vote for any other party - including Reform - will only risk an SNP win."
