Other Fuel System Hoses Lines/piping, And Fittings problems of the 2001 Ford F-150

I filled the fuel tank with gas and drove about 20 miles. While pulling into a restaurant at about 5 to 10 mph I went through a very slight dip. I heard a soft thunk and heard something dragging on the ground. It was not real loud so I slowly pulled into the parking lot. When I looked under my vford F-150 I noticed that the gas tank had dropped due to both straps breaking. The rear of the tank was held up by the hose going to the gas cap area. Fortunately, this did not happen at high speed or I may not be around to report the incident. I called Ford and they state that this VIN number did not have nay recalls. The customer resource person (800. 392. 3673 option 1, 5, 4) stated they were not aware of any government number where I could call in this complaint. I quickly did a web search and found this number so I find it hard to believe they did not know about it. This is a very serious safety issue that could very easily lead to serious injuries/death to occupants of the 2001 F-150.
