Bonitas keeps suspending paid account

I'm a new client at Bonitas. They spend so much time advertising and selling but their customer service and aftersale service is pathetic. It's extremely difficult to get a hold of them. On the first month they charged me double. When I reversed the charge, they suspended my account. It took 5 days to get my account back online. My child and I were left without medical cover for this time. Now I make manual payments and I still get notifications that I have not paid by debit orders although I have cancelled debit orders. My account gets suspended every month because of this even when I have sent through proof of payment. This issue has been going on since I joined in January 2022. I would like for this issue to be rectified at its soonest as it is a huge inconvenience in my life to be calling monthly to reinstate my account for Bonitas' incompetence.
