Un explained charges and no help a month later. NEDBANK

My account parkage was downgraded by the bank system and I started getting charges of R14.00 that would appear multiple times on my daily transactions. I logged a call (***5) with nedbank where by I was told that the Dobsonville branch is the one making the charges and was told it will be escalated. Two weeks later I then went to Maponya mall to get help from the branch, the lady did make a call and she told me Scelo Vilakazi will be able to help, and I should hear from him later that day or week, and three weeks later when I called I spoke to Philisiwe who then told me that the call has not been updated nothing is being escalated and she can see anything on the call log, she then opened a new call (***5) told me that the charges can be reversed by the branch in Dobsonville immediately, I then went to the branch to query the issue, I did speak the branch manager and he told me that Philisiwe is doing the investigation and she should get back to me or make a decision on whether my money is reversed or not. A month later my issue has not being resolved and no one has contacted me with the outcome. So disappointed with the service currently and have an unresolved issue with charges no one from the bank can explain what they are for.
