Wish Nationwide was on my side!!!

Nationwide is a rip off I have full coverage insurance. My car was stolen they told me I have up to 30 days for a rental car but I have to pay for the car upfront and they will reimburse me. In a 2 months span I have had 3 claim adjuster left numerous messages gotten no return phone call finally I got in touch with the new claims adjuster he tells me the investigators are investigating. I have already been thru the investigation process they are just giving me a hard time all around and they don't return your phone calls! I've had them since 2000. You better believe they are going to be dropped like a bad habit
