how is the draw amount

I recently bought 2 bottles of coke and recieved a free coke glass when i got home i gave my five year old son a drink in the glass nd the glass shattered in his hand cutting his finger. I then had to take my son 2 days later to primecare as it was swollen and very red, they told me his finger was infected and he has to take antibiotics for seven days. I think this is a disgrace no wonder you are giving the glassess away for free, i have also heard from other people who have purchased this that there glasses have just broke aswell they are not strong enough. The glasses should be thouroughly checked before being put on a shelf.
