Cadbury Top Deck is smaller but costs the same!!

I purchased the small slab of my favourite Cadbury Top Deck.<br> But when I opened it..I find the slab inside had changed. The shape is different, is much smaller lighter and there's less chocolate. Furthermore there is no weight on the packaging. But I paid the same price as the original slab. It seems as though Mondelez is duping their Cadbury customers, and raking in a profit from this clever ****!!!!!
