Sick and Tired of Nedban****!!!!!!!!!!!!

I am so sick and tired of Nedbank and their horrible customer service. Ive been trying to cancel a debit order for an account I dont use anymore, with no luck, my banking fees on this account is now sky high due to them reversing the debit order monthly while they getting paid via other methods monthly. I refuse to pay all these banking fees due to your incomptetence, you are pathetic as a financial institution. Not to mention their complaints department does not resolve anything , does not even give feedback!
