2009 Jaguar XF SV8

We bought a 2009 Jaguar XF from Max4 cars 3 months ago. This is the 3rd car bought from them in the last 4 years.

The day we collected the car the salesmen at the time told us that the spare keys for the car is in Cape Town with the previous owner and he will send the keys the next week. After various messages to the manager and promises that if they don't get the key they will order a new one we are still waiting now 3 months. The last 2 messages send to the manager was not answered. This is now getting critical as if we ever have a problem with this current key the car will not move. It is all electronics even the gear shift only pops up when the car starts. Can anybody please advise or help.

We traded in my wife's Mercedes CLC 350 for this car and handed the spare keys in wth the car.

A new key for this Jaguar is more very expensive and we cannot afford this.
