Hertz Rental Cars Trapped In Waco, Texas

My daughter rented a car from Hertz to drive to Texas for her husband's grandmother's funeral.  On the way back, they had a flat tire on the interstate and bent the rim.  Hertz at the Waco airport refused to trade them cars because the one they got it from was not a franchise store.  They were told they could go get a new tire and rim and Hertz would reimburse them.  Well, on Sunday, in Waco, TX, there is nothing open that would have both.  They had to spend a night in Waco, pay for a hotel, loose a day of work each and a day of school for my grandson.  They were also told that night that they could turn in their rental car and rent one from that facility.  It would only cost $253 plus $200 deposit because it was 1 way back to Arkansas.  WTF  Roadside Assistance finally got involved.  As of Sunday night late, they were told that their rate of $49 would be honored but they would still have to have a $200 deposit.  Upon arrival Monday morning at the Hertz in the Airport, they kids were told that their credit score was not high enough to rent a car from them.  Again...WTF!!!!  OH, and by the way,, this facility will not take a parents credit card over the phone so that I can get my kids out of that God Forsaken facility in Waco TX airport.
