FNB Connect Airtime Not Being Utilised & Signal Quality

During the course of last week I wrote a review complaining about airtime that hasn't been allocated. It lists on my profile that I have 3995 minutes available, but these minutes aren't been used, instead airtime is being used when making calls. I find this unprofessional and un-acceptable. I have not had a response of a resolution to my previous issue. I also have issues with network reception which was also previously commented on. This morning I have signal on both Vodacom-SA and FNB and when I'm being contacted the call doesn't go through to my mobile phone.
