Lovsted-Worthington Bothell Event Insurance Fiasco

Why they suck:
#1 They delayed signing the policy until 2 days before our event (we requested it 2 mos. in advance)
#2 The policy price quadroupled the day before it was needed, giving us no time to find new insurance. I believe this is called Bait-and-Switch
#3 We prepaid 1/4 of the policy, but cancelled it right after our 1st event and replaced it with USACycling's insurance. So we cancelled it before using what we had alread paid. Apparently, Lovsted-Worthington did not process the cancelation.
#4 We got notices from the underwriter and had to contact them directly (the assured us that the policy was then cancelled and settled up).
#5 Now, 3 mos. later we are getting invoices from L-W for unpaid premiums on a a policy we cancelled with them 2 mos. before the date we had technically prepaid through.
#6 I called them after sending a registered letter, no one returned my call and finally I got a live person who said they'd research it. Nothing yet...
