Airmax 2016 bubble collapesed

Bought the shoes last year October from Totalsports, Cavendish Square. Bubble on left shoe collapsed and the shoes are unbearable to wear as you off balance every step. Nike.com gives a 2 year warranty and Nike SA only 6 months. It is a ******* and I will never purchase any Nike product ever again, I think it's pathetic!!! I picked up that Nike don't respond to any complaint which i find shocking.
