Nedbank staff, in general, are terribly unhelpful

I logged a complaint about Nedbank in September. I received an sms clearly notifying my that Celeste Stanley was my Client Service Manager, detailing her contact details. I emailed Celeste on 8 October and have received no reply. I emailed again today and received a call from Celeste. I explained what it is I required only to be told that she cannot assist me. She also denied the wording of the sms I received from Nedbank. She was very rude and unhelpful. Once my bond is settled I will never deal with Nedbank again if possible. In general the staff I have dealt with are unhelpful and unfriendly, if not rude. I cannot get a response to 1 simple query
