Business ProfileforWestfield Insurance Company

We had Westfield insurance for our home insurance from 08/2020 on our house located at: *** ******* *** ******** ** *****. We sold our house on 06/2024. I wasn't able to cancel the insurance online and I called customer service to let them know we are moving and no longer need their services. I believe I spoke to *******. Recently we received a letter to our NEW house demanding we pay Westfield for a supposed coverage or the bill will defer to collection. The company claimed they kept providing coverage for our old house until 7/20/2024 which then was cancelled due to non-payment. I called their provided number and following a lengthy hold I spoke to 4 different people which were either with Westfield or **** ***** insurance that claimed I was supposed to sign some sort of form and provide them a proof I sold my old house. I was never asked to sign anything before, even when I called to let them know we sold the house. I find it very odd and shady I owe them documents for "proof". I simply didn't need their service. I wasn't able to get anywhere with any of the representatives, they all kept saying "it's our policy". I would like your help with severing ties and a written proof that they will not harass us again. I didn't receive any service for them after the house was sold and I don't want to be harrassed to provide anything or pay for simply cancelling a service (there was no commitment for a specific time frame). They never asked me to sign a cancelation form which I would have done if needed.
