won't stay d behind their commitment or their partners commitment. was overcharged by dollar car rental partner of rentacar. they won't do nothing about it.they say it was a pay later rental which means no guarantee. I had to go to Portland to attend my mothers funeral so I rented a car from rentacar.com[partnered with dollar car rental] and they didn't have the vehicle I reserved. they gave me upgrade and charged me $300,00 for it . have been charged for upgrade because they did not have vehicle that was reserved . I was overcharged for rental because of upgrade and rentacar refused to help me get a refund. if you want what you reserve don't ever rent thru rentacar.com they don't stand behind their agreements'
