FNB Connect issues

The problems started when i wanted to move over to FNB connect month to month contract. FNB Connect called me to take up an offer of 2gb data for R95pm, I told the consultant i would rather go on contract for 5gb data for R245pm, which made her very happy, but somewhere the internal processes at FNB Connect does not work, as I have heard complaints from other subscribers as well. First month, they give me only 2gb (and i requested 5!)+ no debit order was taken off my account as promised. I complained and the next month i received my 5gig , but still no debit orders. I got emails from people at FNB who had no idea what my problem was and i was bounced from consultant to consultant, until they sent me an invoice and assured me the debit order for R585 (R245*2+R95) will be deducted on 1 September 2017. I was ok with that until i looked at the invoice and it seems that they have charged me prepaid rates (R490 for 5gb!) . I am on a month to month contract! I have emailed them last week regarding this issue, but they have still not gotten back to me. I am so fed up with this bad service!
