Fun with insurance... this time car insurance

Fun with insurance, this time car insurance. Esurance sent me an email saying i needed to print new insurance cards (my insurance renews in October and i pay in full). Called them they couldn't find a reason for this notice so said ignore it. The next day got a notice they hit my credit card for 64.00, with no explanation. I haven't changed a thing on my policy, and no accidents or tickets. I called them and they said they never send out an increase mid policy (the net says otherwise). They said they will look into it and get back to me. From reading the internet reviews i am doubtful this will get resolved. Looks like I may be switching insurance companies again. The Justy becomes a classic this year (25 years in NYS) so I can get classic car insruance for it which will lower my premiums.
