sorry but really you need to get in touch with someone over the contractor to state your complaint.Really they will be the only people to help you. If no satisfaction is given all the better business bureau and make a formal complaint
Thanks Janet. Before we move to that stage, we're hoping to get some advice on what part of this may be normal (given that it's relatively fresh) or possibly someone who's seen this before and can recommend a treatment. If all else fails after some fair attempts, we'll definitely plan to go to the BBB or small claims court.
It looks as though the discoloration is in the shade . Does it get any sun? Because it's been my experience that can make a difference in the coloration .
Leave it alone! Plus your "after care" instructions should have included hosing the surface down at least once a day for the first week or more so that the concrete cures slowly so that it does not develop surface cracks and dries evenly. It can take 30 days - sometimes more - to completely "cure."
I've always been told concrete doesn't fully cure for 28 days, so I wouldn't add any chemicals or cleaners to it until its fully cured.

If he is a licensed contractor and refuses to respond contact your state contractor's licensing board online and file a complaint, but I think its too soon, I would call and ask what to do to lessen the discoloration, like should you be wetting it? so it cures evenly.
I agree with above comments. I don't think it is fully cured yet. Definitely don't add any thing to it. That may null the agreement you had with the contractor. Keep documenting and taking pictures in case you do end up in court. But my advice for now is to wait.
Concrete that large takes a long time to cure. Be patient. Wait a full month before being too concerned about the color. If it is still looking poorly call your contractor.
Ird not fully cured . However you need to contact the ready mix company and they will send out a rep. Good luck .
