Great Sports, Inc Safer Wholesale Worst treatment in 84 years Joliet Illinois

I bought a cart from Safer Wholesale in June total price $2900 they cashed the check but did not send the cart until last Thursday.  After it was uncrated and seats and wheels were put on it wpold not start we called them and they told us to use starting fluide finally found that the fuel lines were not hooked up correctly after fixing that and purchasing a new filter we finally got it started and it will run until you take your foot off the gas and it dies.  When you purchase a new vehicle you expect it to run I am 84 years old caring for me son who has had a stroke and cannot walk far and he needs the cart.  The compant will not send anyone to fix it and will not refund our money we need help badly.
