Best Preventative Maintenance Programs in Dallas TX

We did some excavation for them and they didn’t pay what our invoices said. They called our workers liars all so they won’t pay. The owner from one of the properties we did were really upset with their service. I called the owner from that property and he stated they payed what we had said in the invoice seperate from their services. Now I understand why their ratings are so bad because they are some big scammers!
