Terrible customer service. Missed one payment because of some kind of banking error completely out of my control. Was not notified in any way. Received an email with a confirmation number confirming I had made my payment. Then I received a letter out of the blue saying my homeowners insurance has been canceled retroactive for almost two weeks. Called to try to renew my policy and they told me it's impossible and they no longer want me for a customer. Told me that I should have been checking my bank statements to make sure the payment went through, even though I received a confirmation email saying it had gone through. Then the manager got on the line and lectured me about how as an adult I should be carefully confirming all of my payments every month, like he does. Thank god nothing happened to the house during those weeks. Will never do business with homesite again.
