Mowing Craze - Sort Puzzle

I like the game but level 389 has a error you don’t get keys to unlock the locks and get stuck please fix

I downloaded the game because the game advertised it had no ads. More false advertising. And false advertising is a crime. I will be taking action. One top of that this game has the nerve to not only commit the ultimate gaming sin of having both ads after levels AND ads for powerups, but it has the lives system that candy crush games have SPECIFICALLY so they won’t have to have ads. I now have to create a new mobile gaming sin addition to my list because I didn’t know a company would have the nerve to do this. Look. I get it. You guys have to make money to survive. But games make a living without trying to both overload us with ads AND make us pay for things. This is completely unnecessary and people are not going to stick with a game that wants nothing more than all the money in your pocket AND all the time they can squeeze out of you.

Playing and I’m on level 248. I need to uncover the box with the pickax to unlock the blocked box. The blocked box has an 8 on it, and once the one pickax is used it goes to 7. I can’t unlock it further, which means I can’t finish the level. I spent money on unlimited time and now that is wasted since I can’t pass this level.
