AMTRAK PRICE GOUGING 500 PERCENT MARKI UP

I was stranded in Providence on July 7th the only way out of Providence was to pay $235 to a ticket that only went to Stamford Connecticut. I had paid $50 for that ticket the previous day it literally inflated five times the price 500%. Now this can't be legal they keep fluctuating the prices they keep playing games I just paid $70 and I'm not going very far at all.
