Bought boat

We bought a Yamaha boat from them in 2015 and are not satisfied at all with it. The motor is not enough for the boat. You can not do much of any water sports behind it if you have more than 2 people in the boat. We have tried to upgrade threw Bradford for a bigger boat and they are not wanting to help us at all with a good deal. Our boat has only 70 hours and in perfect condition and they want to offer us 15,000 less than what we bought it for and its only 2 years old. The people are rude and not trying to help work with us at all. Also we know others with this boat having the same problems and trying to get help from Bradford and are not having any luck either.In 2015 they were nice,but once they get your buisness,they are done with you!
