Delayed respose or no intelligent response

I called FNB Connect on 26 October to enquire about my voice minutes that were there the previous week and had suddenly gone missing as I wanted to use them before they expire on the 31st October. Got no response and called them again two days later when I was told they DO NOT HAVE ANY TURNAROUND TIME!!! ASTONISHING for a big bank such as FNB. Was told they would look into it. called again in November when I was told my minutes had expired - amazing. I also wrote an email telling the that I wanted to cancel my FNB connect contracts before the new month. Got a call back with NO feedback and NO solution to my request. To date am still waiting for feedback after my third email....
