Hello all - I have a noticeable gap between the ground and the concrete facade around this house. I want to fill in the gap below the foundation with concrete, but how would I do this without creating a big protruding mess? Ideally it would be flush with the rest of the house. Any recommendations?

Need your guys help. We have had this job done by a paving/landscape company for our entrance and not sure what to do. First pic (pinterest) is what we asked for and following pics are what we got. We were told the walkway does not meet the driveway because step up to next step woud be too high, the slope etc. They said they have 40 years experience. We never told them we were going to repave the driveway. Can i get an opinion on this result from some people with experience out there? It wasnt cheap.
