MESSY MESSY SERVICE FOR RMB PC/FNB PW!!!!!

You guys are just horrible. Why can't you reverse a d/o when I request? When everything is actually showing that the debit order is incorrect. My debit order was around R200 and I cancelled the contract with the service provider around May and stopped the debit order but it went through again on the 1st of June. Then I stopped it again via the app. But to my surprise on the 1st of July they debit me R1500 from R200. And when I call to have my money back I get a run around. What more do you need to understand that the d/o was incorrect? I bank with RMB Private Clients but I know it's within your division of FNB Private Wealth. I need this sorted please. Before I decide to move banks. I can't be paying R500 bank fees for such service. It is unacceptable.
