Mark, I concur with Tony's response. Compare the files you sent them, then look at the files they provided you. Generally board houses will not change thermals unless your gerber files do not meet their minimal manufacturing guidelines. To prevent changes to your Gerbers, I would include a Fab note that prevents the board house from adding, changing, or modifying the artwork without prior written approval. We only use this note when designing very high speed boards and the gerbers are "build to print" and may not to be adjusted by the fabricator to match manufacturing tolerances. Otherwise all designs are adjusted by the board house.
