Utility line trenches caving in

Hi everyone. I have several questions regarding dirt work/excavation around our newly constructed home. This "Landscaping and Lawn care" section was the closest section I could find. If this is the wrong section please let me know!

We have several long runs (some 500' plus) of buried utility line servicing our house (electric, water, and geothermal HVAC field). The trenches were dug by our general contractor and then filled back in after the utility company laid the lines. He charged us for the dirt work. The trenches have been collapsing in on themselves. In some sections it's just a minor "bow down" and in other sections it looks almost like a completely open trench again with steep side walls all the way to the bottom. Obviously this is unsafe and I'd like to get it corrected.

My question is: Is this happening because the contractor didn't fill the trenches in correctly, or is this just something that's expected? Would it be reasonable to expect the contractor to come back and re-fill the collapsed trenches at no charge? Whoever ends up fixing it, what should I look for to make sure they're doing it right so that they don't fall in again?

It sounds like normal settlement from loosely refilled trenches...

Who Pays, is between yourself,+ your Contractor...

When I filled my trenches I piled it up so there was a raised berm
Some places sank more then others & the next year I re-leveled the trench line
