I took it to another shop, they replaced the axle again and this time said it was actually broken, and replaced my bottom bracket as well as the threads were stripped on one side. Four or five days later, its just as bad as it was before, and even worse now,
Without looking at your bike I'm wondering if the original bent axle also bent the dropouts to match. Consequently, every time that you feed a new axle to the bike, the bent dropouts reform the axle until it fits them again.
Better than average bike shops will have a gauge for checking dropout alignment. It looks like two big mushrooms that bolt into the dropouts. When the two mushrooms line up perfectly with one another, the dropouts are parallel.
