New car, new problems

[Orbit]

Had this Passat Estate B5.5 for 48hrs and noticed so far the only door that actually works properly is the drivers.

Lock the car and drivers door locks and rear nearside passenger locks.

Offside however are all open.?

Unlock the car and drivers door opens only.

Tailgate wont open, rear nearside now wont unlock, rear offide doesnt open at all from outside or inside??

Headache!! Bloody cars!
