From "working moms just can't catch a break" to "horrendously sexist" — the Internet has spoken out against an advertisement posted by Costello and Costello Real Estate Group of Issaquah.

A Facebook user first flagged the ad, which shows Chase and Jeffrey Costello on one side dressed in suits, with the caption "Full Time Professionals." On the other side a mother is pictured with three childrer; the flipside of the card says, "Available at THEIR convenience not yours."

Now, the ad is getting blasted beyond than the Snoqualmie Ridge area, where it was sent to hundreds of homes. Buzzfeed wrote that the firm's ad was a "cheap shot" at working moms.

Many  others on social media nationwide posted about the ad.

Costello Real Estate Group got so many phone calls and comments about the ad they issued an apology Monday afternoon on their Facebook page. The apology has since been taken down, but here was what was posted:

There are thousands of professional agents working in our area who are also dedicated mothers, including several members of our team. Our original hope with this message was to show the value of having a full-time agent in a competitive market, but we completely failed. We have the upmost respect for moms and working mothers, and we know that the job of a mother is far more demanding than what we do as real estate professionals. Again, we are truly sorry.  - Costello and Costello Real Estate
