OLD Chocolates still within the expire date

I have purchased the tub of quality street chocolates tub 800g (not completely sure ) about two months ago. Knowing the standard of Nestle chocolates I would expect the shelf life to be much more extensive then the estimated expire date as per product. Unfortunately I do not have the proof of purchase and can't exactly remember where it was purchased.<br> I have a complaint about the expire date, the date on the product is 2015/07, when I open the box on Monday 15/6 all the chocolates were rock hard and had such a light brown dust colour it was clearly old and passed the expire date. The soft centred chocolates were completely hard. Not to mention of how poor the taste would be.<br> If someone can please respond to me with regards to this matter, I have a tub of old chocolates that costs R150.00-R180.00 at any retail store I have completely wasted. This is very disappointing and could have been embarrassing as It original bought it as a gift. <br> <br> A response will be appreciated and some explanation as to what exactly I must to with a tub old chocolates<br>
