Nedbank ******** Conduct!!!

I was billed for a honouring fee on a debit order that I reversed. My Nedbank statement shows that the fee of R90 was reversed back into my account but my balance is not showing the R90. I have been a loyal client to Nedbank for almost 8 years and I feel really disappointed by this. I feel ****** and will consider changing my bank because of such behaviour if I do not get a response back ASAP. Totally unacceptable from Nedban****
