Contractors are trying to rip me off

So I need a french drain installed on one side of my house. Had a couple contractors come out essentially they need to dig a 60' trench and lay 60' of sloped perforated PVC pipe. Labor would be $2090 (no problem) and materials would be $700 (fkn lol). Told him he has a deal if I can supply my own materials and pay the $2090 for labor. He tells me that works and gives me an estimate reflecting this.

A couple days later, I call him with my credit card ready to go. He tells me his boss told him I can't supply the materials and they'll only do it if they supply the materials. Maximum bait and switch.

Do you know how much 60' of perforated PVC pipe costs? It costs $54 max at full retail price. They would like to charge me $700 for supplying $54 of pipe. That is a 1,300% mark up. This company literally went back on what they told me just so they can charge me 1,300% on materials. Fkn lol.

Just wrote this idiot an email telling him I don't want his pipe and to fist himself lol. Unbelievable.
