National Tire & Battery NTB, Tire Rip-off Salem, New Hampshire

NTB quoted me twice over the phone. Sent my fiancee down after making sure of the costs....TWICE. .They took advantage of her as someone who is not so knowledgeable of car repairs
I asked at each call what where the extra charges after tire.....I mentioned install, mounting, front alignment, rotation....I asked to include all extra fees.....got a price of 248 for both tires. I told them it would only be two tires and they told me they would bring the back tires to front.....still 248...which the only extra charge was 3 bucks per tire for disposal.....and maybe a back end alignment. The bill was 371.96.....for two low end tires....what da heck??? By the way my fiancee is a buyer for an auto company, and very sharp, but they totally confused her. They charged 12.99 for tire rotation and that is clearly free on their site. When I called to complain the rep took off 50 bucks like.....hey you caught us......but the bill should have been 248 not 320.....RIP-OFF
