I'm sorry they didn't get the pool elevation correct. Looking at the bright side for a second, it's better too high than too low for drainage. What I'd do is cut back the concrete to roughly the house side of the column, and angle the patio from there up to the pool. That will be roughly 2" over 4', which is noticeable but very reasonable to walk on. Ideally you go further back and slow it more gently, but then you take away more the existing patio at the consistent slope. You could also install a drain at the change in angle. But I'd say this cost should be on the PB since the expectation was that it would be a small gentle slope. But regardless, you need them to meet without a step and 2' is too short for a 2" rise in my opinion, for comfort/safety. The slope itself isn't too bad, but it's the change/inconsistency that is not good. I'm not sure why this wasn't identified back on July 11th from your pictures, but that is really beside the point now.
