Terrible Service

An amount of 1896.00 was deducted from my account on the 26.03.2019. I have been trying to call Nedbank to reverse this transaction since yesterday but no one is able assist, let alone answering my call. I spend more than an hour waiting for assistance with no luck. This is very frustrating and Nedbank keeps on making me to want to change my bank. Thier service is terrible.
