Best Concrete Pier Installation in Plano TX

I had basement seepage in my property. 2 months after signing the contract they came and told me they can't do the repair because I didn't make it ready for them, although their salesperson didn't tell me anything about preparation. they wanted to reschedule for 2 months later but I asked for a refund. they charged me $400 just for coming to my house. Don't trust them!
