Hill Hold on DSG 7speed auto SuperbTSI 1.8 petrol

Having ordered a Superb 1.8 petrol TSI delivered in May 2010 I chose Hill Hold as one of my factory extras.

It was pointed out to me by the Skoda Salesman that I didn't need to pay for the extra because it was a standard fitting on the 1.8 TSI so I was very pleased.

I have tried for over one month to make the hill hold function in various situations I came to the conclusion that my car did have Hill Start Assist but did not have Hill Hold

Iam currently struggling to get my Main Dealer to accept this problem and have now stated to discuss with Skoda Customer Care,

Any ideas on how best to proceed?? has anyone else got this problem//
