unauthorized debit order and still waiting for my refund

Miway recently tried twice to deduct money from my business account after I logged a complaint with them stating that I do not have a policy with them and they must stop debiting my account. My bank has now charged me banking fees due to the failure of the debit order as I did not plan for this debit order.

I contact Miway and spoke to Dorkas Mokoana ********** who said she would assist as I provided all the proof they requested on the 20 December 2017 and to this day I have not been assisted or reimbursed for my bank charges.
