Debited on Expired Contract

I had a contract with Lion Minds Wonderpark and they have moved from Wonderpark and their phone numbers, both calls and whatsapp are not responded to. My contract expired in January this year, and I was paying through debit order. The debit order went through at the end of this month and I tried called Lion Minds with the hope to get through. Unfortunately the voice prompts informed of the volume of calls the call centre is receiving, at 9:00 am. I received a WhatsApp link- still my problem is not resolved because I cannot proceed with the bot. Shouldn't contracts be automated on the system so that when it expires it gets to be automatically removed from potential unnecessary debiting of clients. As mush as Lion Minds have a good product for tutoring school kids, their administration & finance/accounts departments leaves a lot to be desired. DISAPPOINTING REALLY!!
