Drive tall stakes into the ground and tie those 3 ring things off to them. As you have discovered, they are mostly worthless. ;) You can then tie the plants off to the stakes for more support.

Search cages here for many discussions on how to make great cages to use for next year if you wish.

I not only bought the cheapy cages from menards, I bought the SMALL ones. Big mistake. Currently, I have a second cage upended and tied on top to give me a bit more height. Now, I have 6 foot tall bamboo poles tied to some of the worst cages for support, and other poles to hold up branches that escaped the cage.

I bought texas tomato cages and they have been fabulous. My plants are big and bushy and reaching 6 ft tall and they have bot budges. They also collapse flat for storage.

Thanks, people!

I don't have any stakes, but I had a wooden garden trellis. I dug/pounded that into the ground as deep as I could and tied a cage on the front and a cage on the back, and loose branches to the trellis itself.

It's not the best solution because these plants are only going to get bigger and more weighty, but it works for now.

Meanwhile, I'm considering the Texas tomato cages for next year.
