Update:
There is a board at the top rear of the refrigerator to hold it down. What happened was, while traveling the refrigerator tilted forward forcing the board to give just enough that it released it. When the refrigerator fell back, the board was now between the refrigerator and the wall. Preventing it from straighten out.
So all I had to do was unscrew the board and the refrigerator fell back into place. I replaced the board on top of the refrigerator and all is back to normal now. Thanks to all who tried to help.
