Thrifty Rental Car Pick Up Feb24/15 Drop Off Apr.9/15 Through Hotwire

I reserved a car pick up Feb.24/15 drop off Apr.9/15 at Orlando Airport. Agent told me I had to return car to airport March 24 then rent again. The agent was unprofessional, bullying and rude. I am 2 hours from airport , the only driver and my husband is disabled. This is not the rental details we were given on email through Hotwire. If I had know that I would have to return the car early and rent again I would not have rented with thrifty.Have spoken to thrifty 5 times today no help. I have emailed and spoken to Hotwire . They tried to help but couldn't get through to customer service. Why can't I just phone to renew or at least go to closer rental place to renew
