Installing coilovers should not damage your axles. There’s more to this story. How did they break you CV axles?

When i took it to the shop they said it was in shapes they werent suppose to be in because of the coilovers. I put new cv axles in and may try again i just dont know if its going to ruin the axles or maybe they were just bad at the time and needed to be replaced

Is your G a X model? Meaning is it AWD or standard RWD?

I'm with BlackBetty on this one. There is more to the story as coilovers should have little to no effect on CV joints. Front CV's (on AWD models, maybe), but the rears should not be affected at all.

Please provide more info...

Still unclear as to what the shop deems "all messed up" and what they allegedly repaired/replaced. What was the diagnosis: torn boot(s), clicking in turns, thunking noise over bumps...? CV joints themselves are pretty reliable- it is usually the rubber boots that fail- but external factors can cause failure.

Typically, lowering a car a few mm's here and there will not affect the driveline too much. However, if your car is "slammed" the change in driveline angle can create additional stress on the CV joints, the axle, and the hubs- all leading to potential, premature failure.

All depends on how low your car is set at this point. I have no clue what a "S" or "Z" shape refers to. What kind of shop is this?

Hopefully others can add to the topic.

I lowered it from stock to below the tire line, I guess about 3 inches. We replaced the axles with cv boot because it was needed, torn boots. Missed a retaining clip and that was causing clunking and damage where it went into the driveshaft(?). Once at shop and on lift they showed me the angles is the axles. They were not straight in and the angle into the back of the wheel portion was bent, —/ vs —|, if that makes sense. Said it was only a matter time before I hit a bump and they broke due to that angle

A 3" drop is too much, especially for a AWD car. Most folks drop these cars 1" or so. IIRC, anything over 2" is pushing the limits. If you want the car slammed like that you will need custom axles- at least for the front but likely all four corners. You either have to reconsider your drive height or research custom axle sets that will take into account the different driveline angle.
