Have same exact problem and didn't solve it yet - but, hopefully, on my way:) There's a technique called "concrete raising" - Google it up. They drill small holes in concrete and pump some filler in (sand, clay, whatever)I I din't yet find local contractors - but 2 companies had online request forms, which I filled out. No response yet (3 days). I'm hopeful - but keep looking. That's how I stumbled upon your question.
Will post again if find out anything interesting
good luck

The technique is also called mudjacking, slabjacking and pressure grouting - use these when looking up a contractor on Google maps or local.com

Apparently there was no rebar or wire put in to hold the concrete together. Drill holes in the high part for rebars going to the outside supports and repore conrete. But, what will keep it from sinking again?

How do I know if my concrete repair job requires mud jacking?
Mud jacking is a concrete or foundation repair method that is typically used in regions where the ground tends to settle, causing foundation issues. A foundation repair expert can tell you whether mud jacking is needed, a technique that basically fills in the settled area with pumped in dirt and cement mix. Mud jacking is what you need if you have sinking or sunken concrete driveways, patios, walks, steps, or garage floors. Concrete mud jacking fill the voids under the sunken concrete areas with a slurry that’s made of clean soil and cement by forcing this grout into the voids and this lifts or raises the sunken concrete back to the correct level and the grout fills the voids and stabilizes the soil so you won’t have to worry about the concrete sinking again.
How do you get the area of 6 inches x 12 inches concrete cylinder?
To find the area of a concrete cylinder, you typically calculate the lateral surface area and the area of the circular bases. For a cylinder with a height of 12 inches and a diameter of 6 inches, the radius is 3 inches. The lateral surface area is calculated using the formula (2\pi rh), and the area of the two circular bases is (2\pi r^2). Thus, the total surface area would be the sum of these two areas.
