The city has ousted the contractor providing social services to homeless families housed at more than a dozen Manhattan hotels.

Children’s Community Services was quietly replaced in July with Acacia Network Housing.

The city pays hotels directly for rooms to house the homeless while it contracts with nonprofits to hire case managers who are supposed to help clients find permanent housing, apply for benefits and offer referrals for child care and other services.

A spokesman for the Department of Homeless Services would not explain why the group had been booted.
