FNB Connect - Not Connected Yet :-(

I have since terminated my contract with MTN and have decided to move over to FNB. I was successful in migrating and porting my MTN number over to the FNB SIM that was handed to me at FNB Dot at Nicolway Mall. I have dialed *147*1# on my phone with the new SIM to apply for the Ultimate package to which I was unsuccessful "No cards to authenticate" I have called the FNB Connect number 147 and have went through to FNB Dot for assistance. Being a FNB customer for +- 5 years, I then went onto my profile and had linked the SIM that I already have to my account which was successful. I then received a sms saying that I will be contacted by FNB for delivery of the SIM. Call was received on the 29th and for delivery of another SIM card. What must I do with another SIM ??? All I need is for FNB to debit my account and allocate the minutes/data/sms. After speaking to so many people at FNB Dot and on the 147 number I am left without a solution. It seems as that the staff are not well equipped on how to sort this out!!!!
