Terrible service

My contract expires on 2 June 2016, I called in to ensure that I dont have an auto renewal on my contract. Vodacom apparently cant handle a request to ensure this can be done, I need to phone in during May to do so. when I call in May they'll tell me that I need to give a few months notice and they'll continue deducting a debit order. On top of that the call centre agent puts down the phone on me.<br> <br> Well done Vodacom
