johnny steamer carpet cleaner

I called this company I previously used to clean to sets of stairs one
going upstairs and other going to basement.
Johnny was a bit late just having come back from a previous job but went
straight to work having advised him carpet on basement stairs would
need extra attention. I did have a clean up bit of mess he left on floors
but carpet did look cleaner and it wasn't until it was dry that I noticed
a smell that wasn't there before. I can only assume he came in with
dirty equipment from previous job. I called someone else to have it
redone. Won't be calling this company again. Really disappointed.
