The Robinson's said they were upset by the hospital's attitude
The parents of a Leicestershire man who died after being sent home by Stafford Hospital have said they will never recover from his death.
John Moore-Robinson, from Coalville, died in 2006, at the age of 20, after a fall from his mountain bike.
Doctors at Stafford, which has been criticised by a report into its care, said he had bruised ribs but was later found to have a ruptured spleen.
His family has said they deserve answers into why he was sent away.
A report by the Healthcare Commission found the hospital's "appalling" emergency care resulted in patients dying needlessly.
About 400 more people died at Stafford Hospital between 2005 and 2008 than would be expected, it said.
Mr Robinson's parents, Janet and Frank, said that after the fall at Cannock Chase in Staffordshire, he was rushed to the accident and emergency department.
Despite being in extreme pain and vomiting, a doctor decided to send Mr Moore-Robinson home.
Mrs Robinson said while in the house on his own he was in so much pain he called an ambulance.
"The ambulance came but when he stood up to open the door he had a heart attack and they couldn't do anything for him.
"The post-mortem revealed he had a ruptured spleen and his stomach was full of blood.
"He should not have been sent home, he should have had a scan at Stafford Hospital.
"They just didn't take into account the accident and they told him he just had bruised ribs and then sent him home to die."
She added that a letter of apology from the former chief executive Martin Yeates had made things worse.
"The last part of the letter reads that 'we can now put it to the back of our minds and move forward'.
"But how you put the death of your son to the back of your mind and move forward?
"I will never, ever put it at the back of our minds. John was our son and it is the most dreadful thing in this world to lose your child, for your child to die, for your child to die at the hands of someone you put your trust in."
An inquest into his death returned a narrative verdict.
The new chief executive at Stafford Hospital Eric Morton has apologised for the pain caused to families.
