AMEX PE Upgrade/Companion

Bit of a stupid question really. I have a VS White Amex card but have never really paid attention to what I should receive by way of benefits. Lurking at the back of my mind was the fact that if I spend 10 grand in one year and I should receive a PE Upgrade voucher or 15 grand and will receive the companion fare.
I have spent well over 15k in a year and received nothing. How does one go about obtaining these vouchers? If it is automatic then something has clearly gone very wrong. Does anyone know if these are issued respectively if there has been a bit of a balls up by either the folk at MBNA or FC.
Any advice or guidance would be greatly appreciated.
