First off, I have a 175 wall banger, and I have been cleaning carpets for years this way. I had 3 Cimex and sold them all. I like my wall banger. 
It's not the machine it's the person working the machine.
The smell I would bet is from over wetting the carpet. As with anything, knowing how to use the tool in the tool box is 60% of the job and using quality chemicals and pads/bonnets makes up the other 40%.
This is nothing more then a medical office hiring the janitorial service with the lowest price and nothing more or maybe the office mgrs. brother needed a job.
Either way, I walk away from bids like this that are price driven only.
In all my years of carpet and janitorial cleaning (since 1986) I have never caused a carpet to stink.
Also, I don't know which area you are in cold or warm but a lot of times these buildings like to shut off the heat when done for the day. I have one cleaning acct that does this and we have to wear our coats when we are in the building to clean for how cold it is.
In a few days the smell will leave because the carpet will dry. In the meantime, the office staff just has to hold their noses.
In life it boils down to: you get what you pay for.
