Business ProfileforAllstate Insurance

July 2023 I paid for my insurance coverage for the next billing cycle ($234.10) ending aug 2023. I cancelled my service with them aug 24, 2023before my next billing cycle on aug 25, 2023 Received a collection notice several months later for $111.18. Submitted dispute with copy of cancellation letter, proof of new coverage starting aug 24, and of my payment going through for the final billing cycle. Collection agency on behalf of Allstate says it was rejected due to adjustments, but unable to clarify what these were and that I would need to discuss with Allstate. Contacted Allstate several times who say I must deal with the collection agency. After several back and forth attempts Allstate customer service says they will do a billing history breakdown and history request, and that they have no way of possibly connecting me to the billing department. Multiple times they send me an email saying they have looked in to my request, but are unable to reach me, without any call attempt, and that I must contact customer service again. Repeatedly telling me they cannot provide any information on my account due to it being terminated. **************** again says they cannot connect me with billing department but must submit another request. In the end they are not providing me any breakdown/proof of a debt owned after countless attempts to do so.Would like for them to provide this proof or remove my debt from my credit report on the three major credit reporting agencies.
