Princess Maid Service

I have to give Princess Maids a solid C.
I purchased their services through Groupon for three 2-​hour cleanings. On all three visits, they left in under 2 hours. That would have been fine had the cleaning been complete but it was not.
After the first cleaning, I called the offices to explain my issue and negotiated an extension to the second cleaning. They agreed, but didn’t make good.
I noticed a bowl that had gone undusted and before the last cleaning, I ran my hand around it and gathered the dust in a nice clump. I figured they’d have to see it. Nope. Still there.
The bottom line for me is that they didn’t live up to their obligations: I paid for a total of six hours of cleaning and didn’t get it. From my perspective, they needed to be looking for things to clean to meet the agreement. Instead, I got rushed, incomplete work.
Since I don’t need to manage another project, I won’t hire them again.
