your problems are your problems

I went to nedbank n1 on the 23/05 to have a charge reversed and I was told, that it cant be done today as the system can only process a day after and I had 30 days to raise the query. I managed to get time and went to nedbank milneraton and was told \oh sorry"we no longer reverse since the 25/05/2015 this is new policy and I asked why I was told I had 30days. I then requested to speak to the manager who rudely told me\"" its not my problem\"" that's the new system. 1. I went to nedbank on the 23/05 and its YOUR system that cldnt process not me. . why should I be affected"
