FHA 203K non Streamline project...hired a contractor who's not responsive

[Terrilynn Kelley]

FHA 203K non-Streamline project... we hired a contractor who's not responsive, they don't follow-up on what they are going to do therefore continuously stalling the project, we haven't started the project, and we need to be completed by 1st week of August. Can we switch contractors? We are on a tight deadline to complete the project any advice? Thank you in advance...location Pittsburgh SFH.
