Honda of Aventura

i have been buying my cars from this location for past several years. i had a great experience. but they have changed ownership recently and they are not truthful. i sold my car to them and leased a new car from them they are supposed to give me check, they have been giving me the run around for past 2 weeks, i have asked for explanation of charges and deal structure they sent me to to different person. i think they raised the value of the new car that i leased in order to buy my car at the price i was asking with out telling me and then rushed me to sign the documents with out explanation.
