"I thought it was pretty disrespectful, extremely disrespectful," said Mr Reinsfield, who blamed the error on fight promoter Duco Events.
"No one ever phoned me to ask if he had retired and then they go and stick that straight up? This is coming from Duco who, let's face it, have made a lot of money off the back of Shane's blood and sweat."
Director David Higgins said Duco accepted responsibility for the error, which he attributed to Minto getting carried away.
"We were happy to adjust the commercial because we don't want to offend Ken and Shane."
Mr Higgins said it was unfair of Mr Reinsfield to imply Duco had exploited Cameron.
"Shane has made some good money on our promotions. We've paid him close to a million bucks or heading up that way in the few times we've worked with him, so there are no hard feelings as far as we are concerned. Boxing is a business where there is a lot of talk in terms of building a promotion. Hopefully they don't hold a grudge, but that is up to them."
Minto said he had apologised to Cameron over the commercial when the pair met at the recent Super 8 fight night.
"I'm not the type of person who likes to slander people or say mean things," Minto said. "It was kind of a catchy thing I guess to promote the fight but I can see why they would be mad. I said 'man, don't take no offence, it's just promoting the fight'. As you can imagine he was pretty sore. He was like 'I'll let this one slide', but he was trying to break my stones a little bit."
Mr Higgins said Parker, who is training in Las Vegas, was unaware of the dispute over the commercial.
"Joseph was present at Fight For Life and saw what Minto did to Cameron first hand. If he didn't end his career he came damn close to it."
While Cameron has not confirmed any plans for his return to the ring, a blockbuster showdown with Parker now appears a distinct possibility.
Mr Higgins said Duco had presented Cameron with a six-figure offer to fight Parker, which remained on the table.
