No regard for new clients

My membership was due to start in September. I requested for debits to go off on the 25th of the month. In Aug I receive an email stating that I’ve fallen behind on payments. 25th Sept two debits go off on my account. I emailed enquiries only to be told that Bonitas doesn’t debit in arrears and so I’m paying for September and October. I ask for a refund and get told to rather speak to my bank. I called my bank to reverse 1 of the 2 debits. My October debit goes off as scheduled and two or so days later my membership is suspended for nonpayment. I email again just to be told that I have an unpaid debit order. I don’t feel that the team looked into the matter. To tell me to pay the money is also not sufficient. I still haven’t received feedback from the agent who was assisting me. It’s bad enough that I’m on a 3 month waiting period, but handling my debits this way is costly and beyond frustrating
