Terrible experience. This company has a Groupon offer- STILL up for Certified Cleaners (as of 11.21.18)Two, Three, or Four Man-Hours of House Cleaning with Two Cleaners from Certified Cleaners (Up to 53% Off)which we bought. Then they tell us it is an error and only one cleaner. They will NOT honor it, and made US go to Groupon for a refund. Obviously they dont care about customer service- Take it up with Groupon, Certified, dont put your customers in the middle of your error.
