FNB customer assistance is the worst!

I have downgraded my Premier cc account to Aspire cc account on reference CAS-***4-C1J1X6, this reference was closed without downgrading my account to Aspire. Today i received a Premier cc delivered but the Documents signed is for Aspire cc. I have been transfered to 8 different people via the sevure chat and i have phoned twice *** and there is no one at the extention. I need someone to urgently call me and fix this mess and im not paying for another delivery.!!!
