Merry Maids

I am very disappointed with this company. I use them every October to clean my parents condo. They are snowbirds and I like to get it professionally cleaned before they come down for the season. I have paid $120 for the past 3 years and this year when they called for my payment they told me it would be $200. When I asked why they said they charge by the hour and these girls must have taken longer than girls in the past. She also told me some of their cleaner are faster than others. What kind of cleaning company does that? They should charge based on what they are cleaning, why should I pay more for their slow girls when some of their other employees could do the same job for $80 less?? will never use them again!
