BANK CARD AUTHORIZATION PROBLEM

FNB customer care is the worst! I tried getting my card verified with Skrill and it kept on saying 'Authorization Failed'. I then opened a case about it and they told me my my bank card issuer (FNB) was the problem. I then contacted the FNB customer service but I couldn't really speak to anyone because the machine kept me waiting for the next available consultant then I decided to visit my nearest FNB branch. No one knew what I was talking about and they told me to call again and speak to a Forex consultant I then did so and the person also didn't know what I'm talking about. I tried writing FNB an email last week but they never responded... this has been going on for almost 2 months now please do something about this someone from FNB !!!!!!!!!!!!!!
