I cant add gas to my car. It takes maybe 20 cents then starts to spit fuel out. on 2000 Chevrolet Camaro

The Gas tube is full like its the tank itself is totally full but theres no gas in the tank. The repair guys at Chevy told me to go to a different gas station but that made no sense and didnt work. its like somethings blocking it.
