A National Cleaning Service Sent Several Crews to New Jersey

A national cleaning service sent several crews to New Jersey and New York after Superstorm Sandy in 2012.The crews were trained to deal with mud,mildew,and all the problems of making a flooded home or building inhabitable again.The print and media ads that the cleaning service ran stated that the company had a patented system that would remove all unpleasant odors from flooded structures and leave a clean smell.Its sales reps who contacted owners of apartment complexes and shopping centers promised that the crews could come into an average size of apartment complex and have it looking and smelling like new in two weeks.Several people who rent apartments in the complexes that the service cleaned have commented unfavorably on the sweet smelling air freshener the company used to mask the smell and noted the moldy odor was still perceptible.Also,the time required to clean a complex was more like four weeks instead of the two as promised.Which provider gap does this example describe?
