Sterling Quality Cleaners

We have been using these guys to clean our carpets in our home for 4 years and up until recently were pretty happy with them.
Last 2 times we’ve gotten pretty substandard service. We put up with it once but not twice:
* Carpet was left filthy. Dog hair and grime left on the carpet. Lots of it.
* We pay the minimum «3 room» rate ($ 125). Normally they make up for this by also cleaning our couch and easy chair — usually takes the guy 5 extra minutes.
* Cleaning guy refused to do the couch, even though he was in and ready to leave after cleaning the one room in 15 minutes. He said, «I have other places to clean and I’m running behind»
* When we showed him the dirt we were able to scoop off the carpet, he said «if you’re not happy, just take it up with my manager about making it right» and took off.
* We called the manager, mentioned the still-​dirty carpet and the couch not getting done. He said, if you want the carpet cleaned again it’s $ 125.
* We said, we just had it cleaned today, and it’s not clean. Will you make it right? He answered, if you’re not happy with us, call another cleaner, and hung up.
I guess, sadly, avoid these guys, they have lost their integrity.
