Right Cars was HORRIBLE

After completing the paperwork and being told that the coverage on my BMW M6 wasn't enough to cover the Nissan compact I was renting, the agent tried to tell me I HAD to get their insurance. I had called my insurance company (USAA) before my trip and they assured me my coverage was sufficient. When I told the agent (W. Curri) I would check with my credit card company to make sure everything was legit, he said he would not rent me the car and pulled back all of the paperwork. Leaving me stranded and scrambling for another car. I will NEVER do business with this company again and if asked, I will tell any/everybody about my horrible experience with them.
