I've been with Nationwide for ages... ever since I started driving at 16, and I'm 31 now. When I moved down south from New York, Nationwide doubled my rates (~600 per year to ~1300 per year). Like any sane person, I asked why my rates went up so substantially, and they said that there are more accidents where I moved. I'm pretty sure I checked at least another insurance company, but they weren't much better.
Well, after buying a home, I went with Nationwide for that too, and the home insurance rate is actually pretty good compared to others. It's about $1300 per year and other companies go as high as $2000 per year. However, Nationwide has been a rather horrid experience with their home insurance. I received a letter stating that my policy was being cancelled because I didn't have a latch on my gate, and that's required for an area with a pool. I was baffled, because I have a latch. I gave them a photo and received their photo evidence... their inspector literally took a photo from the other side of the gate where you can see the back of the latch, but not the latch itself. :|
Unfortunately, this tale doesn't even end there. They stated that everything was fine after I provided them the evidence, but I still received a letter in the mail stating that my insurance had been cancelled, but would be active until the month is over. I called them up, and they stated that I would receive another letter stating that the previous cancellation notice would be revoked. I did receive that, and I suspected that everything was fine... until I received another letter a few weeks later. This time, Nationwide reimbursed me for my entire year's insurance rate. :| Yet again, I called them up, and they said that my insurance policy wasn't supposed to be cancelled, but it got cancelled anyway. They told me to cash the check and that I'd need to pay them back because they couldn't possibly do anything about the check after issuing it. (Seriously? No Hold!?) After that, I decided to shop around for car insurance again, and I was able to get a good rate with Geico for about $620 per year with even more coverage than I had with Nationwide. Although, one thing that bugged me about Geico's setup is that you can't determine multi-policy discounts until you actually have multiple policies. So, State Farm may have been a better option as their home insurance is cheaper ($120 per month vs. ~$128 per month) with a car insurance policy.
Anyway, I was rather glad to put a stop on my next payment to Nationwide of $140 for auto insurance and go with a measly $55 payment.
