Business ProfileforIDI

IDI has been harassing me to pay for a service that they are no longer providing to me and threatening to send me to collections even though they are the ones who violated their own contract.Per my contract I agreed to pay $350/month in exchange for IDI providing me with search credits on their website for one year. In case of non payment, the contract states that they are entitled to charge interest, but that's it. I kept my credit card on file as per the terms of the contract even though I was no longer using the search credits halfway through the term of the contract.In September 2022 I was unaware that my payment didn't go through and IDI suspended my service. I believe that is a violation of the terms of the contract and therefore voids it. They keep making a big deal about my contract and how I am supposed to pay whether I use the service or not, but they are not providing me with the agreed upon service anymore, so they are not following their own contract.I do not think it is right for them to keep asking for payment and keep sending me invoices for a nonexistent service.I believe the most I would owe them is a prorated amount for the days of service they provided in September up until the suspension (which was roughly two weeks worth of service that they did provide).
