Business ProfileforIndoor Billboard/northwest Inc

We have had ************ floor mats serviced by Indoor Billboard for many years. I recently contacted Indoor Billboard in September of 2023 and asked to cancel my account. The person I spoke to, ********, said that she would let someone know that I wanted to cancel. On October 18th 2023, Indoor Billboard once again came into our store and swapped out our mats with clean ones even though we said we wanted to cancel. I was also charged, again, for this service. On October 18th, I once again called Indoor Billboard and spoke with ********, again, and said that I needed my account cancelled. I asked them to come back, pick up the mats, and refund the credit card charge. I received a call back from ***********************, who said that we couldn't cancel because we signed an agreement, back in 2020, extending our services for several more years. I would need to send them a certified letter canceling my service, and I would need to buy out the remainder of my contract. I told him I never signed a contract, and he emailed me a contract signed by one of my employees, not by the business owners (my wife or my self). They are trying to keep my in a contract that I didn't sign. The contract is null and void.
