Repeated Verification Document Requests (OH)

I mailed in my verification documents initially, but received a letter saying they needed all of the documents that I had already sent. I uploaded them to the Benefits website. I received the same request letter. I've sent, emailed, uploaded the requested documents.

In early October, I got an email dated in September requesting the documents again with a September deadline. Today, I received the same request email with a sent-in-September date and an October 9th deadline.

I wondered if anyone else has experienced this.
