Dark Chocolate Alpen

I purchased a pack of Dark Chocolate Alpen. Advertised as 'new' I was looking forward to eating my way through all those lovely chocolate swirls as shown on the pack. On opening the pack, I realised there was not one chocolate swirl, let alone any sign of chocolate. In fairness to Weetabix, the brand owner of Alpen , they did respond with apologies saying that the pack had appeared to have slipped through the chocolate adding stage and as a result contained no chocolate. However, I remain sceptical. I will use the vouchers they sent to me to purchase another pack, as I still don't believe that there will actually be the amount of chocolate / chocolate swirls advertised on the pack. I would be interested to learn if anyone else experiences similar and whether they agree on the content of chocolate.
