Bad service at Hyundai Hatfield

I bought a new car with Hyundai Hatfield and was told that it comes with a memory card. When I went to collect my car as I drove off I noticed that the card is not there and I was informed by the sales man Steve that I'll get it a week later coz it wasn't invoiced. Now it's almost 2 months later and I am still without my card. I called in today to follow up on him and no luck of me getting my card. I spoke to Steve and requested him to put me through to his manager and I was told that his white and the matter will come back to him.

The service I got from that branch was really unpleasant from the collection of the vehicle being told its ready and next its not and now the card is missing.

I wouldn't recommend them to anyone because you can't even speak to the manager to escalate your matter.
