FNB Call centre disaster

I bought golf clubs on the credit card promotion as advertised on their website in May. It has been a whole month with hours of telephone conversations to actually get FNB to hold up their part of the promotion. Nobody at the credit card department even knows about promotions or could help me. Every single time I phone they just 'escalate' my query... which in my experience translates to 'your not my problem anymore'. I am a full-fledged ambassador of FNB but this is probably the worst call-center experience I have ever had. I'm probably on the phone every day for 1 or 2 hours and still, no help could be given.
