Double debited - bad service

My credit card debit order was doubled debited on the 20 Nov by FNB. I called the FNB credit call centre 21/11/15, where after speaking to a rude and confused consultant, I than spoke to the team leader Romansha, after a total call of 37 min... Romansha, was going to have an escalation load for a reversal of the double debit and moved funds over from my budget to straight in order for me to withdraw and put into my cheque account (not held with FNB - and this was made know to both persons spoken too), which as a result of this was overdrawn. However due to the daily limit on the card I was unable to access all the funds on the day, this was not mentioned to me, so the exercise of making the funds available was rather pointless. the next day i tried draw the remaining funds an error occured and there was a reversal of withdrawal, the funds reflect as available, but are uncleared. On the 23/11/2015 i called the call centre again trying to get an explaination of what happened, the consultant requested for Romansha to call me back which to today was not done.I had to call her today only to find after business day 4 I STILL HAVE NOT RECEIVED A REFUND AND STILL UNABLE TO ACCESS FUNDS
