Jacked around on my tires

Oh sorry yeah kinda venting.

I found out my wheels had been discontinued. After searching around for a couple days I found a shop that had 2 in stock and they were not the right offset but after talking with Denny they would work so I ordered them. In the process they asked me if I wanted to apply for 90 same as cash financing and for poops and grins I said sure. I got approved for a pretty good amount so they asked if I wanted to add tires to my order and I said sure if you can find me matching tires for a decent price. The response was Sure we have them in stock so I said great throw em in. They sent over the contract and I signed it wednesday last week to be shipped out the next day. Well Friday came and went with no tracking numbers. Found out they didn't have the wheels in stock they ordered them from the manufacturer and the sent them to the wrong warehouse so that caused the delay. Finally shipped everything last night then said Oh by the way we didn't have matching tires here is a picture so I looked and they sent me 2 completely different tires the fronts they are sending me are the Federal Formozas I said yes to, but the rears are some federal SUV tires with a funny looking tread pattern. Needless to say they don't want to change the tires for me.
