Sterling McCall Honda

I previously purchased a 2007 Civic from this dealership a long time ago so i went back to see what new models they had for 2017. I loved the redesigned 2016 civic so i decided in the end to just go with a silver LX model. The car salesman George Torres was patient, informative and made my car shopping experience overall a very pleasant experience. HOWEVER, the financial employee JOSEPH A BOGUHET who got all our paperwork done is extremely unprofessional and an outright [non-permissible content removed]. When signing the papers he did nothing to explain what each paper really meant. I understand that it was a late Saturday night but he was more worried about making a buck and getting us out of there as fast as possible. My Honda and all certified cars come with a 7 year/100K warranty which is what i believed i was signing but he automatically signed me up for a completely SEPARATE 7 year/100K warranty that i never once asked for. The worst part of it is that he charged us 2800$! for it. So i did some more research and i can get a better Honda 120k mile warranty with a 0$ deductible for about 1K. That's almost a third of the price he sneaked into my contract!!!! The only reason he finally confessed that i could cancel was after i asked like 6 times. At first he kept insisting that i keep it and that there was probably nothing he could do because the paperwork was filed. Which by the way was a complete lie when i called the bank who financed the loan. And to finally turn this into a absolute nightmare he also snuck in a "Resist All" customer care box into my contract that he informed us "came with the car". Not once did he mention in was going to cost me an absolutely ludicrous 1000$. When i confronted him about it he kept insisting that i received it with some sort of "coupon". I told him that couldn't be possibly be true and that you can't call something a coupon if there was no discount from a set price and that you CHARGED ME 1000$ FOR IT! That honestly seems like fraud. I asked nicely if they could just take it since i never even bothered opening it. They told me no and it was the one thing they couldn't help me with. Even though i went back with the box the following day before i even was allowed to drive my car out of there. So lets this get straight. Honda can cancel a 2800$ warranty after my first bill/before 60 days but they can't take back some insanely overpriced kit that i once never opened or asked for? I've lost all interest and respect in this company/dealership and the way they treat their customers. My friend and father were there to witness the whole thing and my friend told me that Joseph must have no sense of morality for doing something so slimy to someone who has happily buying a car from them. I will be doing every last thing possible to leave complaints/negative reviews for this dealership. If they refuse to help me out with something so simple as taking back an overpriced box then all their future customers deserve to know the lengths they will go to cheat a customer out of their money. EDIT: I was told they couldn't take it back because the Resist All was applied to my car. That wasn't true and i don't know why they keep using a different excuse. First it's because it's because of "the contract", then it was just "we can't take it back" and now due to" it being applied"? What really happened was that I came back on Monday to try to return it and i was informed by my salesman that they weren't even close to attending my car. It wasn't even certified yet and i didn't get to drive it home UNTIL Wednesday around 12:45. I arrived there at about 11:00 and they were barely getting around to detailing it. So don't go around telling me it was applied on a Monday way before it was certified and cleaned/detailed.
