Questions about flooring contractors

[Lisa Pigno]

New construction, Homeowner paid for all flooring and bath and kitchen tile materials up front 32k to flooring company, then paid 8k for labor to flooring company when half done, tile in showers 95% complete,flooring company now wants 6k to pay laborers, wood floors have not been ordered by flooring company or      installed ( were paid for up front included in 32k over 2 months ago) don’t know whether to pay the 6k or wait until wood floors complete and we are satisfied, does it sound normal that floor company needs us to pay his laborers, also floor company has taken back all tile that was leftover that I paid for in full up front, without asking me if I wanted to keep it or get refund, Thank you
