TNT Carports work not completed and damaged property nationwide Nationwide

We received a quote for a metal building on line late April 2015 and paid our deposit of over $800.  We waited 6 weeks and finally the first of June the contractors sent came to put up our building.  They did not speak English so it was difficult to communicate with them.  They started drilling holes in the concrete prior to measuring or squaring up the metal frame.  The holes were in the incorrect places and new holes needed to be drilled in our new concrete pad. The first day the workers were there about 6 hours and took frequent breaks and drank alcohol on the job.  The second day they came late and worked till almost midnight.  As they were getting close to them saying they were done, in the dark, they called out my husband to show they did not have door handles.  They also said once they left no one would come back to finish.  Their were large oil stains on our concrete from their trucks and the job site was a mess.  Metal shavings from the screws being drilled in and cutting of the metal went into our new pool. We did not see the mess or the other things not finished until the next morning after they were long gone.  I think they work at night for that reason.  The edging at the top does not line up, the rubber at the bottom of the roll up door was cut, the doors had large black marks across them, the cement was damaged from the extra holes, no handles to close the doors, a roof that leaks like it has a hole in it and damage to the drive way and pool. 

I have been communicating with them he issues since the day it happened.  I stopped payment on the check and told them several times in writing that as soon as it is finished and the damage repaired I will pay.  Several unkept promises led me to get my pool repaired ($1300) and the door knobs put in so we could lock it.  The building still leaks and the other items remain an issue.  Today they promised someone would show up and no one did. I did however receive a collection notice from them for my balance.  Fix it and I will pay.  I am getting a lawyer.
