Neville ran an artistic blacksmith business before the shooting limited his ability to work. He said he wanted "answers and an apology" from police.
"I know I have to deal with the poisons in my body, and with the constant pain, but I've always struggled with the things that could've been fixed.
"I haven't had an apology. I never had a chance to say my side. The Independent Police Conduct Authority spent a lot of taxpayers' money making an in-depth report based on one side of the story ... I didn't even get an interview."
Taylor said police didn't return calls when he tried to reach a settlement last year.
The decomposing metal was taking a toll - he finds out this month if an operation is needed on a neck gland affected by shrapnel.
"I look like a banana cake on an x-ray."
The authority found in 2012 armed offenders squad members were justified in firing at McDonald, but there were significant problems with the operation, including a lack of effective command and control.
An authority spokeswoman said Neville was not interviewed because he had already made two statements to police, and given evidence at an inquest.
A police spokesman said Neville received a payment from police after the shooting for hardship and suffering.
"Since that payment was made there have been no discussions regarding additional compensation."
