Chiefs trailed for much of regular time but found a way back into the game in the 76th minute through Leonardo Castro in the 77th minute despite going down to ten men in the 64th minute.
However, a late strike from Siyabonga Vilane condemned the Amakhosi to another shock defeat to lower league sides and would have brought back memories of their Nedbank Cup final defeat to TS Galaxy in 2019.
"It's embarrassing. On a personal level I don't think I have ever lost to a First Division team in 26, 27 years in football," Hunt told SuperSport TV.
"But they got a lifeline. We had so many opportunities but you've got to take them. When you play against a team like Richard's Bay you've got to score first but they got the upper hand.
"We committed two bad errors at the back but in saying that I've got to take a good, hard look at the squad. You can't be delusional about these things. There's a lot.. I don't want to say too much.
"We had numerous chances in the first half but we didn't make that final ball count and even when we went down to men we still had numerous chances and you've got to do better.
"A few people you give a chance here and there and obviously proves me right. And then we make the changes but then obviously the one or two that came on need to do better.
"We've got to work a little harder. We've got to make situations better. We've got to work a little bit more. We just want the ball to feet all the time.
"We turned the ball over in the right-back position, we kicked it straight to the guy and they turned over and went down the other side and you look at situations and you think 'Why he's there when he shouldn't be there? Same player for both goals.
"I know what's in front of us. I know what's in front me so we've got to be better.
"It's been like from that from the start. We've got to have more legs in the team, you know? A bit more mobility. All these type of thiings. But we've got to get though and we've got to grind away and turn the corner and go again."
