Multiple debit orders

I am devastated with number of multiple debit order transactions to my bank despite manually paying my account. After a returned debit order on the 27th May, on the 28th I paid manually via easypay method, and also sent proof of payment to update my account. When I check my account the money reflects on my statement but they repeatedly sent debit order deductions everyday, they accumulate unpaid fees of R100 everyday I have contacted Finchoice via telephone , email and log request but os either i get no response or I am told I must wait for my account to update. This is the first time I experience this and I am devastated beyond my control. Today as I am writing this the account still reflect debit order sent to your bank, I am horrified by this , it is costing me
