Credit card payment

I had an amount (R495) coming off my credit card for the last year , which i did not ok . When i first noticed the issue 5 months ago i contacted FNB credit card department , they confirmed that there was an amount coming off sometimes 6,7 times a month and at the end of every month the credit card dept would phone me and ask me to pay my outstanding amount . Eventually i informed them that i would not be paying the outstanding amount until this issue was resolved . I was told to go to my local FNB (clubview ) to file a ********** case. I did so , i filled out the forms in detail and sent it off i also then got the consultant to cancel the credit card , this clearly hasnt helped either . When the credit card department over the next month hassled me consistently about paying the over due amount i then filled the forms out again for ***** stating my case to FNB and still not even a phone call back to date. I am still receiving calls from the credit card department to date. UNTILL this morning when i was amazed to see that my other FNB account was emptied without my authority to pay my credit card and low and behold R495 deducted from my credit card
