Can't terminate Credit Card

I called ABSA to terminate my credit card with them on 16 March 2016. I was instructed to pay a settling amount, which I did and it was confirmed that my account was paid in full. I was informed that it will be terminated but that someone from the card division would contact me in 3 to 5 days regarding my termination. I contacted them again on 24 March 2016 as no one had contacted me yet. They tried to put me through to the card division that was supposed to contact me but they were busy, but I was informed that they would contact me later that day. No one contacted me that day. I sent an email to ABSA on 30 March 2016 and the automatic reply stated that I would be contacted within 24 hours. It is now 46 hours 47 minutes and I have still not been contacted. When I check my accounts today I see that my Credit Card is still active and I have been billed a service fee for the new month.
