No service book nor holiday a year after purchase

Last year around March I bought a car from S4 Auto, as part of the package there was a complimentary holiday. <br> <br> I noticed there was no service book which I sensitised both the dealer principal and sales agent and I was told it'll be provided and I'll be able to pick it up from Infiniti Melrose .<br> <br> It's almost a year, I gave up on written correspondences which I've exchanged back and forth to try and get the issue resolved. Eventually after having to drive to the dealership a couple of times I was given the holiday voucher which when I tried to redeem I discovered it had already been redeemed. <br> <br> So here I am, no service book nor holiday voucher. Multiple emails sent back and forth, guess it's fine as long as the dealership made their more than half a million sale the customer doesn't not matter at all. <br> <br>
